    This is amazing..

    This is amazing… got my Key within Minutes and worked flawlessly.Customer service was spot on and they responded almost immediately with answers to my questions even before I made a purchase.Highly recommended.

    As Described

    Based on the previous reviews, I was a little concerned I’d be getting a fake key, but it was quite legitimate. It’s OEM, meaning no bells and whistles — you break the seal on the cardboard envelope to get the disc, scratch off the gold leaf on the side of the package to reveal the key, and enter the key when prompted during installation. Easy to do, no special knowledge required, and no insidious garbage software bundled with it.

  4. Justin

    Worked perfect for me.

    This came in a cardboard sleeve, the sticker with your profuct number is attached to this sleeve. You will no be able to attach this to your machine, so do not loose the sleeve! I’m not sure why all the reviews on here are saying they recieved fake/boot leg discs. Mine installed fine and is fully activated.

  5. Steven

    Worth the extra cost over regular windows, especially for gaming or picture/video editing.

    Got this for my gaming PC build, it’s as close to bare-bones as you can get with major operating systems, works great for me.You can customize it to fit your specific needs, there are some great options.

    The Product Key Works

    Bought it directly from cjkeymall (The CD version). Installed the software from the USB media thumb drive created by other computer with Windows 10. Received the CD with the product key covered by the silver material. Scratch out the silver part and type in the product key to and finished the activation. 

  7. John H

    My favoite windows version so far

    I love windows 10, it’s easy to install and it has excellent dual monitor support.The only thing I don’t like is forced updates but I can understand why it’s that way.

    I purchased this Key after creating a partition on my MacBook Air for Windows 10 from the windows .iso file. I was honestly surprised by the price for the software considering buying a key from Microsoft costs about $70 or more. I received the key via email roughly 24 hours after purchased and changed my product key information and activated no problem.Thanks! 

  9. James Fox


    Worked as advertised, thank you for saving me some money!

  10. Kevin Faber

    the provider gave easy steps for installation

    Although it took several attempts to correct and complete the purchase, once received, the provider gave easy steps for installation. The product was well worth the investment. I would order again from this company.

  11. A. Armstrong

    Getting better as Updates come along!

    Installed in box build and works as it should. No licensing issues and all updates install perfectly.

  12. Steve L

    Works fine, once you find the product key!

    I bought this to install on a new Intel NUC system I was building, choosing Windows 10 Pro because I wanted to use Bitlocker disk encryption. The DVD worked fine for the install, but I was momentarily confused as to where to find the product key. Inside the packet is an “authenticity” sticker which has a small scratch-off square that hides most of the product key. The type on the sticker is so small that I did not recognize at first that’s where the key was and had to use a magnifying glass to read it. Note that you don’t actually need the DVD – you can download the Windows Media Creation Tool to create installation media on a USB stick if you want. 

  13. Leichter

    Microsoft Windows 10 Pro 64 Bit

    Much better than 8 (which was horrible IMO), about equal to 7. The spying issue is BS and overblown so don’t believe those reviews. Bought it for a custom PC.

  14. Kindle Customer

    For a NEW computer build there really is not a problem with this windows 10 disk.

    *** Please Note *** This is a windows OEM disk and it is used for NEW computer builds. If you are not building a new computer ( without going to a long lot of other details) you can either wipe your old hard drive or just install a new hard drive and install the disk.. The language pack in this version of windows 10 is in British English but that is easily changed by using windows 10 after the install..To save time ,just go to this You Tube video for directions on how to do this in windows 10.[…]

    5 stars for Windows 10, BUT, I don’t know where else to post this, don’t buy Windows 10 from cjkeymall. You’ll get the UK English version or worse, some sketchy looking copy.

  16. nathanso

    As expected, but hard to locate the activation code!

    Look for the activation code in tiny print on the small barcode label.

  17. JP

    Easy install.

    Installed with no issues. Was put on an SSD drive. After you add product key it completes in less than 40 mins.

    If you’re doing a custom PC build and don’t have a DVD drive, Microsoft has a free tool for creating a bootable USB thumb drive for installation which you can use, then enter in the product key that comes with this DVD and it will work.

    Best ever Windows Install experience

    The best Windows release yet. Very quick install ( 13 minutes not including update downloads which tok about half an hour) and all the drivers just worked out of the box.

    BE AWARE! Windows 10 is great, but SELLER GOODIEHUB is selling DVDs that ONLY SUPPORT ENGLISH UK installations. You can still use the product key, but you will need to create your own installation media with the Microsoft Windows Media Creation Tool, and be sure to create media that has your preferred language (ENGLISH US, in my case) as an option. I wish I’d known this before I purchased from this seller, as this is adding an extra layer of hassle to the process of building a new PC for my client. It is also wasting my valuable time.

    I always get a little worried buying an OS on the web. Got what I paid for. No fuss registering.

    As far as I can tell I got lucky and got a totally legit copy of MS windows 10 pro. Others have reported fishy looking disks, pre-opened items, already used CD-keys, however, I may have gotten lucky!If for some reason my key comes up in use I will report back, but I am nearly 30 days in without issue – and all of my packaging looked legit compared to the YouTube videos I watched on how to check authenticity.

  26. Ghazy

    Fast and trustworthy

    Thank you so much I I received the key through the email and my copy is genuine now

  27. Thomas K. Reidy

    The best OS I have ever used

    The first computer I purchased in 1993 was running Windows 3.1. The other day I was watching some old episodes of the “Computer Chronicles” on YouTube and had forgotten what it used to be like to use a computer. So much improvement.I remember the OS’s that were terrible- 95, ME, and Vista (Vista was a mess until SP-1 was released), but between all of the crap releases there were the good ones- 98, XP, and 7. I do wish Microsoft would have kept MCE in the OS, but there are alternatives that work out well (Kodi, Plex, and Emby). And, as far as I am concerned- the only version you should buy is the Pro version.

  28. Jes_074

    Good OS which lots of potential to grow

    Windows 10 is good OS and it’s AOL for the 21st century. Just go back and look at the ads for AOL and you’ll agree. I do enjoy the touch screen interface as it actually works unlike with WIN 7. I am still getting used to everything being isolated for security reasons.

  29. Amazon Customer

    It is what it is

    Got it for $99.99 from uhh… “Head of Software.” Package arrived very well wrapped, tape was questionable smelling, didn’t use the CD inside but it appears to be legitimate. The key worked perfectly and is now bound to my Microsoft account.The OS itself is awful of course but… can’t play Metal Gear Solid V on Arch Linux.

    Worked perfectly. Loaded it on a slightly older I7 Dell laptop that had Windows 7 on it. Used the options to repartition the drive and it installed with no issues. I did buy the pro version to get the encryption but my laptop doesn’t have the hardware support for it so check your hardware before buying if you are getting the pro edition.

    Windows ten pro hear it’s boss. Easy to use and perfect for gaming!! Plus it makes for some d*** good office utility as well.

  37. Rachael


    Great alternative than buying directly from Microsoft. Packaging looks a bit off compared to “Official” Microsoft products, but works just the same. Would highly recommend for anyone installing a brand new OS in their computer.

  38. t reviewer

    Easy to install, works well.

    I used this one when I replaced my hard drive. It was very easy to install, and worked well. I’m very satisficed with the results!

  39. Kam

    No issues.

    Installed easy, working with all my components.

  40. NavyRet

    All in all a GREAT deal.

    Worked perfectly to upgrade a Win8.1 computer to Win10 Pro. Took a couple of hours, but everything went through without a hitch. AND the price was right – way less expensive than buying a license from Micro$oft – plus I have the actual disk if I need to reinstall. All in all a GREAT deal.

  41. Tan Kuan Khoon

    The version of Windows to upgrade to, if you haven’t done so.

    Installs smoothly and without hiccups.For users with Windows 7, 8 or 8.1. Well, you have a free copy from Microsoft via your update function so you can stop reading this review and go try Windows 10 for free.For users who are planning a new PC, it’s time you start shoring up our dwindling PC sales and give the mobile devices a run for their money.

  44. TN

    Bought it just so I can have “the best”

    I only bought Windows 10 pro 64bit because I like to have “the best”. I’m more of a gamer then doing work so most of the “features” I don’t need. I feel like Windows 10 is more for a laptop because of ok the go stuff.

  45. Luis G Coreas


    Very good product

  46. Techno T

    Windows 10 is the one you want!

    At the time of writing this review (Feb/2017) is the only seller of this product, which is 100% trusted. I purchased 2 copies of Win 10 64 bit OEM and both came 100% legit and sealed in original packaging. The bad reviews you see are from 3rd party sellers.Windows 10 x64 bit is great. It really is leaps and bounds better than Windows 8/8.1. It takes some getting used to over Windows 7, but after using it about a year I genuinely like it more than 7. Updates are always roll-ups, which is nice because no matter how old your copy of Windows 10 is, when you update, you will get a single OS update that includes all fixes.If you’re buying Windows, you really should get Windows 10. It may even be the last actual version of Windows, so better to learn it and get used to it.

  47. Christopher Selvik

    Excellent product

    Excellent product, thank you.YouTube – TexWegian1990

  48. Scott Oberley

    It worked!

    Disk and code arrived promptly. I had already went to the windows website and downloaded the latest version and had it loaded. I then input the code sent and it all worked. This was one of the better prices I found for windows 10 Pro.

  49. Sameer

    It works

    It works. These are for custom computer builders or if you want to upgrade your current Windows 10 Home license to Professinal license on a Dell, HP, Samsung, Asus, etc. computer. This is for 1 computer only. If computer breaks down and is retired then this product key can be tranferred to a new computer you build or buy. If your computer has a Windows 7 license product key then you do not need this. Your Windows 7 key or Windows 8 key can be used to upgrade to Windows 10. You can download the Microsoft Media Creation tool for creating a Windows 10 disk or flash drive if you have a Win. 7, 8, or 10 product key already.

  50. Maverick 1

    Love it

    I Bought a new laptop that had windows 10 home edition on it. I did a clean install with this Windows 10 Pro Edition and it boots up much faster without all of the bloatware that used to be installed on it from the manufacturer.

  51. Caleb Kierum

    Key worked perfectly

    The key worked perfectly. I didn’t even end up using the disk that came with it.I am not sure why there are so many review that claim that the software key does not work well. Perhaps there is a small chance that this could happen but hopefully they would give you your money back.I used this key to install Windows 10 on my MacBook Pro 2017 using Apple’s Bootcamp tool. It didn’t take too long and was very easy to install.

  52. Ron Krogel

    Good value

    Basically an OS, what I really liked was the sticker for the machine so when I go to sell it it looks like a genuine OS and materials also look genuine as they should.

  53. Raymond V. Lewis

    Windows 10 not much more to say

    Windows 10. What more to say. It installed so my computer is more than a large paperweight.

    The version of Windows 10 Pro that I received was older version and had none of the updates, but for the price that I got it for was worth the little extra trouble to down load them. I’m happy with Windows 10 Pro as operating system and have had no problems with it.

  55. Luis Giron

    Fast delivery and Easy to installation

    Windows 10 pro OEM was easy to installed. I did not have any problems. At the beginning I was a little doubtful thinking that it was not a legal copy. But after inspection of disk and packaging it as a real OEM from Microsoft.

    Buy from cjkeymall to be safe

    This review is for the OEM Windows 10 Pro 64 bit version. After reading all the negative comments/issues I bought this with cjkeymall being listed as the seller. That worked as I received a double white sleeved DVD. The outer sleeve had the typical legalese. The inside sleeve had the COA sticker with the activation key partially hidden by a grey Microsoft scratch off. I used the key on a fresh install and the activation worked without issue. I then peeled the sticker off and put in on my computer case as the license is not transferable anyways.The disc and packaging has 2015 copyright dates but outer part number sticker had build date of 2016 and version 1607. After installing it shows release version 1607 as well.

  57. Omar C.

    Worth it. Not reverting back.

    It’s a great OS. For all the complaints of a skimpy app store, having all the important apps plus thousands of others on the desktop is a huge plus. Plenty of quality games as well in the store. Privacy concerns, while valid, can certainly be avoided. You can opt out of just about everything as far as I know. You don’t even have to log in with a MS ID if you don’t want to. Local accounts are available. So, you can have the privacy of Windows 7 with the power of Windows 10. Local accounts were available on Windows 8, but it was less obvious as to how to choose that option when setting it up on install than it is now. Windows 10 is more transparent, but it could do a better job at asking if you want to choose a local account or sign in with MS ID instead of assuming that you are signing in with a MS ID. Stability is close to flawless.Edge has come a long way, and I’m looking forward to PDF markup capability coming in the fall update. Of course you can use your favorite browser, whichever that is. Cortana, however, is limited to Edge.SMS phone integration has gotten better, but still limited. You can reply to sms in the notification bar, nowhere else, unless you use Skype as your primary messaging app on a windows phone. Not sure how that works with Android/IOS phones, but I know you at least get notifications.Speed is fantastic. Boot to desktop time is typically 10 sec or less with an SSD. Pretty quick with a standard HDD as well.

    You got my computer working really great

    Thank you for helping me out with this product

  60. S. Belton

    No issues with activation–cheaper than buying direct from Microsoft.

    This is an OEM version of Microsoft Windows 10 Pro, meaning per Microsoft’s licensing agreement you should technically only install this software as part of a computer built from components, not a Dell, HP, etc. The software was shipped and sold by cjkeymall, came in a white envelope containing the CD and the sticker with the product key hidden behind a scratch off for security purposes. I had already downloaded and installed Windows 10 Pro from Microsoft’s website–I was able to use the product key delivered with this software to activate my copy of Windows. Unlike prior reviews, I had no issues activating the software, I simply clicked “Change Product Key” typed in this product key and within a few minutes my copy of Windows was fully activated. Not sure why others had issues, perhaps they were trying to use this software on store bought computers in violation of the OEM license.

    An excellent operating system that greatly exceeded my expectation at replacement Windows 7. Stop the waiting and make the move to something new and improved.

    The best thing since Windows 7

    I recently bought an ASUS ROG laptop that came with Windows 8.1 on it. Having come from Windows 7, I wasn’t too keen on 8.1 . When I read that it was Windows 10 ready, I decided to buy this OEM 10 x64 along with an SSD to give the HDD an extra push. I had experimented with Windows 10 TP for work and was satisfied with the results enough to take the plunge.The results have been great. Being a gaming PC builder, I have nothing negative to say about Windows 10. It’ll be even better once game developers start optimizing for Direct X 12. This is the way to go if you’re considering the jump on a machine that had previous versions of Windows installed or even building a new one from scratch. The biggest issue I’ve seen so far is people’s security software being too outdated where it just is not compatible with 10, in fact it actually causes issues with network connectivity. That’s not Microsoft’s fault, FYI.If you’re having issues with this disc, you really ought to consult with your hardware manufacturer in ensuring you obtain the correct drivers for this install. ASUS did not provide all of the drivers that were Windows 10 ready, but the nice thing about Windows 10 is that it allows some flexibility in compatibility with 8.1 drivers. I was able to mix and match a combination of drivers in this way and it has worked just fine. In fact, my laptop would often times have a BSOD when running games on 8.1 . But, ever since switching to 10, that is nonexistent! And, the even further optimizing on an SSD makes it boot insanely fast and load applications without hesitation. Well worth the buy.

    Arrived the next day! I had to upgrade my main board and Processor due to a bios fail 🙁 This also caused me to need a new windows product key. I ordered this OEM version to save a few bucks. I put the key in and windows was activated in seconds. No issues! Thank you cjkeymall!

    Crisp Clean OEM software

    I was skeptical about the product. Had gotten bootleg OEM I am still trying to get straighten out. This was clean. Quick installation. I was an OEM, years ago (Pentium 1 and 486). This is a simple install even for an enduser.


    Great OS

    Good copy of Windows 10. It installed clean on a desktop and everything went smoothly. I like Windows 10 MUCH better than 7 and especially 8. Best version of Windows yet.

    GEAT PRODUCT —– BUT- Not enough initial information for purchaser.

    Too bad cjkeymall took this product offline. People were complaining that they couldn’t get an activation key label that was legible or that it just didn’t come with an activation key but that is not how this product works. (Notice Microsoft label over key code.) You just simply go thru the installation dialog boxes when it is being installed and skip the entry box for the activation key and click “activate later” and simply use the product while connected to the internet. Eventually, (usually within 72 hours), Microsoft will automatically activate the product over the internet and give you a product key in the operating system. You can look it up later and write it down or keep a backup copy later by using the activation key app.Reasonably priced and works GREAT!Will not work for an upgrade though. Only a clean install on a blank hard drive. (Best installation anyway!) So BACKUP, BACKUP, BACKUP.

    Windows 10 is the Best!

    Windows 10 is the best! It comes with a disc with windows 10 installation on it and a product key. I popped the disc into my computer and started the installation. For some reason my computer crashed during the installation so I had to reinstall windows. After I had the OS up and running, I tried to activate it with the product key but it wouldn’t activate. This is because I entered the key in during the first installation and then my computer crashed, so windows thought that the key was already being used. But Microsoft is awesome about this stuff and I called there costumer service and they had windows activated in no time! Even if you run into the worst of problems Microsoft or their community can help. Windows 10 is WAY better then 8/8.1 and I totally recommend it for anyone who wants a great OS this is reliable and easy to use. Five stars all the way!

    After 3 or 4 failed attempts at upgrading from WINDOWS 7 to WINDOWS 10 (…ALWAYS STALLING/GETTING STUCK-for hours-…AT THE PROMPT …”GETTING UPGRADES” [about 32 to 45 {+/-} upgrades maybe involved here, BUT they will take only a few minutes/NOT hours after upgrade installation]….), …I FINALLY SUCCESSFULLY (!!!) INSTALLED THE WINDOWS 10 UPGRADE. The secret…1. “TEMPORARILY” TURN-OFF ‘WINDOWS AUTOMATIC’ UPDATE IN CONTROL PANEL (Reason: These two (2) operations seem-to conflict with one-another.)2. TURN-“BACK”-ON WINDOWS AUTOMATIC UPDATE “AFTER” COMPLETE UPGRADE INSTALLATION.I ORIGINALLY got a second computer exclusively to only “test” WINDOWS 10; NOW [ 🙂 ] it’ll be my main computer. I planned to,WINDOWS 10, upgrade another, notebook WINDOWS 7, computer, the same way later.

    Windows 10 Pro does very well for me. I order my copies from cjkeymall. I have purchased keys from in the past and I will probably will again it is much cheaper but, the last key I bought I had to call Microsoft to get it activated because the key showed as previously activated….for a $3000 build I’m not taking a chance spent that much might as well spend a little more and get an OEM key from MS that is worry free. I’ll save kinguin for the budget builds.

    Nothing like the Real Thing

    When Microsoft promoted the free Windows 10 Upgrade, I was one of millions Windows users that upgraded from Windows 7 to Windows 10 for free. Months into the upgrade I experienced performance problems and s few crashes – my coworkers (Microsoft certified users) experienced the same situation. Therefore, before switching over to Apple, I decided to purchase an official Microsoft Windows 10 Pro 64-Bit system DVD. I also have reveal in this prose I am a proud owner of a Mac Mini, no negative things to say here.It is good to have an original Windows 10 running in my workstation.Thank you.

    Buy the OEM DVD disk for a brand new build with empty SSD

    Came up and worked great, very quick and easy and arrived quickly after order. A bit confusing to know what to purchase for a full, at home, personal build of a ATX Asus motherboard and empty SSD. Of course I also had to have a DVD drive as part of the build to read the disk … but it only costs $20.

    This program has had a lot of hate when it came out

    This program has had a lot of hate when it came out, and understandably so. I have been using windows 10 however for around 6 or 7 months now and I actually like it. I think alot of the misconception was rumors and unfounded speculation about spyware and malware that windows has been infected with. I’ve turned off features and specific things to help not get bothered by stuff, and they actually do leave you alone. I however did not like being injected with the GWX virus, and i do say this because it was linux who actually allowed me to delete the trouble file on the hard drive before i switched. I loved 7, but am glad i skipped over 8.1 and its counter parts.So far I’ve not had any major problems, memory leaks, or otherwise. I’m a programmer, and can really damage a system if I put my mind to it too! 😀

    It’s all good!

    After my old hard drives failed, I decided to replace the upgrade version of W10 [ upgraded over W7.] with this clean install of W10 Pro. Now that my system is back to being fully restored, I have noticed a significant improvement in performance and stability. There were no issues with the installation or registration of this software. The OS has a very good set of utilities for setting up most of the hardware. My computer is a 2011 X58 based system, and I was able to install 2 new SSD’s and get everything running at peak performance with ease.

    First off, dont be that moron that posts reviews about the actual operating system. If you are too dumb or not tech savvy enough to have done your research on the product before you actually ordered it than you deserve your failures. I work Global IT and beta test the OS’s from Microsoft and can say this is a far superior product than Win 8 was and you should upgrade. I can’t fix stupid but I try and inform people they are in hopes they fix themselves.As far as the actual product the OEM version of Win 10 pro. It is a great price. I spent the extra $20 to order it from cjkeymall as I usually do for most products if given the choice. If being a sorry cheapskate and buying from an disreputable seller, you probably get what you deserve. As the saying goes, you get what you pay for.

    Works as Expected

    Bought this item before reading the negative reviews. When I read several, I was worried that the code would not work.After building my new system, I installed the Win 10 Pro x64 version. Not having an optical drive on the new computer, I used an old Win 10 Pro x64 USB thumb drive installer.Everything loaded as expected, and the code worked the first time. Once the new machine connected to the Internet, the OS activated automatically. OS is now fully updated and current.Would definitely buy this again if I needed it.

    Windows 10. Most people have to have this.

    Installed Windows like it should. I didn’t install with touch screen, so no review input there. I have been building PC’s since the early ’90’s, so no tech support required here. The stability rating I will assume means how well Windows run. That is subjective as I have seen Windows 10 run like a scalded dog and I have seen them run like a sloth. I built this PC using medium hardware. Not the cheapest, but not the most expensive either and she runs great like that dog that got scalded. I also am an IT expert, so I know how to keep a computer running smooth.I only buy Windows when I build a PC for someone, or when I build me a new one (every 5 or so years, and yes Microsoft, I play by the rules and buy a new copy of Windows when hardware is new) to run alongside Linux. I only keep Windows on a machine to keep current so I can fix other people computers. If you are computer savvy in any way, I would recommend to try out a Linux Distro and see how you like it.

    What sorcery is this…?

    I don’t understand how the seller is selling genuine Windows 10 Pro for this price. BUT IT WORKS and I don’t care to know how.Emailed link points to .iso of Windows 10 from Microsoft’s web page, burn onto CD, install with supplied code. It’s really simple as that.

  112. Kindle Customer

    My son chose it and likes it.

    I’m resistant to upgrading to Win10 but this was for my son’s computer that he was building and he chose Win10 specifically. He likes it. He’s 16 and this is for a computer that plays a lot of video games, and spends time on YouTube, Facebook, Netflix, and Spotify. Just keep in mind if you’re looking for support for other programs, the instructions probably aren’t for Win10 (yet) or even Win8, so you need to know your system well enough to be part of your own tech support team.

    Seems legit

    A family friend lost her hard drive containing her licensed Windows 8 recovery partition. I tried many different approaches and tricks, but could not recover it. I purchased this to (hopefully) install an activated Windows 10 on her new hard drive. The Windows 10 installer I used offers both “Home” and “Pro” versions, but it automatically detected that the license was for the “Pro” version and installed it without prompting. After ensuring that the install applied all available updates for Windows 10 Pro, the operating system remained “activated,” so this key appears to be legitimate. Although Windows 10 itself is questionable, there’s no doubt the $16 I spent on this license was well worth it.

  115. Derek Thomas

    My new favorite OS

    The best way to describe windows 10 is that it incorporates the best qualities of windows 7 and windows 8. Everything runs and opens quickly and it feels very natural to navigate.

    To be expected.

    Heard bad things about Windows 10, and I haven’t experienced any problems. I dropped $2500 on a gaming build I built myself. I’ve installed, Steam, Twitch/Streaming stuff, multiple games … and haven’t had 1 driver issue or anything yet. It is Microsux, and within their wealth you’ll find an equal amount of greed, but that’s too be expected in 2017, corporations makes cents …. not sense. We all know Micosux could make a light weight, minimal fluff, badass operating system perfect for PC users … but they’re not … they’re going to make one just stable enough to fill with stuff from their buddies. A few tweaks to the options and you can make all the corporate ‘please stfu’ go away.

    !Students! There is a free version for students. If you are a student, definately check it out!For those who are not interested in the education edition.

    Legit key for a fraction of the cost

    To those reading this review;Yes, I am posting an actual review of the transaction, which is a Windows 10 Professional 64 bit Serial Key. I don’t know about ya’ll, but I was DEFINITELY wary of the potential of fake reviews considering how cheap the key is. Considering the price difference of the DVD sold with an authentic key was over 100, I decided to roll the dice and see if it worked.The key installed was for a new install: so I was NOT upgrading from a windows 7 or any other version and I was installing Windows 10 for the first time on a brand new hard drive.I held my breath as I submitted the key that was purchased and was actually surprised that it had worked.FYI, the key will be sent via email from the seller after purchasing.If this review helped, please be sure to click yes below!

    So Many Features and a Smooth Installation

    Well I had to update from Vista64 because some of the software and drivers are not longer supported. So I bit the bullet and ordered a new hard drive, a hard drive switch box, and Windows 10. The install went so smoothly that I decided to do my wife’s computer also in the same way. So now we both have dual boot systems with a push of a button. Windows 10 is awesome.

    Best Windows Yet Despite Upgrade Nag

    While the nagging updates would get a 1-star review from me, Windows 10 is the fastest, smallest, and overall best Windows OS I’ve worked with to date. I prefer it to every prior version, including XP. This kit is great if you’re building your own system.

    This was a nice new/ clean clean desk-top installation that took all of about ten …

    First, I have to say that I am not a computer professional, nor am I a newbie to building computers and using the operating systems. This was a nice new/ clean desk-top installation that took all of about ten minutes to complete. Being that I am making a huge step up to Win 10 from previous Win versions, there is a bit of a learning curve when using Win 10. The challenge is finding everything that used to be in familiar places that is still there but either in different places or structured a little differently. Everything is now app-based, similar to our phones, and if you can get used to approaching the operating system like you use your phone, it makes things a little easier.Some have been critical of forced updates and data mining, and other things. I chose the pro version because it lets you schedule updates. I have not had any problems. As far as data mining and other things are concerned, I really can’t tell, and can’t really say that it is more or less than what Google or anybody else collects. So overall my rating of five stars is accurate and honest and I have no reservations in recommending it to others.Edit/ addition: I must add one very important detail: After opening the packaging, you will find the bar-coded information on a sticker. Also on the sticker is the product key, which is covered by some kind of material (similar to what is on a lottery ticket) that must be scratched off to reveal the product key. Caution! DO NOT use anything metal to scratch this off or you may damage the key code. It is better to use a finger nail to scratch lightly, a little at a time until the key code is revealed. Also, once the key code is revealed you will notice that it is printed with one of the smallest font sizes I have ever seen. Get your magnifying glass out, you will need it (I’m not kidding).

    Didnt support my video card but there is a workaround

    Fresh install on a 4 year old PC. First installed the software but no driver for my video card was available under Windows 10. Video worked OK but the resolution wasnt right. There is a driver available for Windows 8, however I couldnt get it to install. So I downloaded the Win10 software directly from Microsoft, burned the iso to a DVD and reinstalled. This time I could install the Windows 8 video drivers and it worked. The COA sticker is included. Mine was authentic.

    Let’s Say My Fingers Are Crossed…….

    First I went ahead and got this as I wanted a copy on a older type media that I could install from a DVD. This fit the bill. I’ve installed OEM versions before (My Windows Vista was one), so this shouldn’t cause me any problems. I plan on holding off using this copy till my Win 8.1 Pro system updates to Win 10 Pro as I have reserved the upgrade and then see. I tend to “hedge my bets” and if things don’t go so good on my Win 8.1 Pro upgrade, then I can wipe the drive and I have a version ready to go. (I tend to like clean installs anyway, but wanted to see what developed with Win 10 Upgrade.) So now I have the OS and a new WD Velociraptor 1 TB drive to put it on…..I should be ready to go no matter what…..!Update: If you plan on using this to update an OEM version of Win Home to Pro you will have a problem at first. I found this out when I got a used computer with Win 10 Home on it and tried to use this to upgrade to Pro. It wouldn’t let me. Tried a number of times thru the “change product key item” but to no avail. Finally discovered how to do so by searching around on the web. It seems that you must have an un-activated Win Pro on your system first then your key will be accepted. There is a default key that upgrades Home to Pro BUT doesn’t activate it. This is where your key comes in. After you’ve used the default key to get to the un-activated Pro you then select “change key” and use the one that comes with your DVD and it will then activate the OS with the new key. A bit of a round about way to get your purchase activated but it worked for me.

    This review is primarily seller review, not product review. The product key’s that this seller has are 100% legitimate, I found nothing wrong with the key they gave me.As other buyer’s have stated, please ignore the fishy shipping date, you’ll receive your 25 digit product key within 24 hours of purchase. I received my about 3 hours of purchase.Although, I would have loved to have received a physical copy of Windows 10, it’s just a personal preference, so I can not honestly deduct any stars. But beyond my personal desires, this seller is safe.

    SOFTWARE and CODE were good. Microsoft had to get involved to upgrade Windows 10 to PRO.

    I purchased this product, and it arrived fast. It did not install as expected, but this is not the fault of the seller!!! **Please note**… The OEM/COA code was good for this product but would not recognize from inside the software. I contacted Microsoft support, they connected to my device, upgraded to Pro manually and confirmed this is a good code! The code issues upgrading seem to be on Microsoft’s end. The tech was more than happy to quickly help me upgrade which tells me this is probably a known issue at Microsoft.VERY FRUSTRATING and time consuming for me as a tech business owner as it looks like they may have blocked a set of license keys. Not fair to bill my customer for manufacturer issues. If you read this and have issues installing…contact their support. I did so though chat and it worked well.I will also follow up with Microsoft on this issue, and AMAZON so they know they may have a set of legit software that has issues installing.

    It’s legit – no catches, no problems

    No problems, license key email showed up fast, in about an hour. This is the way Windows should be sold. Download the installer from microsoft and away you go. MS has really put in some hard work into Win10.I did get the black screen on boot issue because the laptop has a second video card. I would have hoped MS had resolved that issue. FIX: Just boot to safe mode and disable the extra video card.As a systems engineer I am just amazed that everyone in the universe is so willing to pay $100+ for Windows.I am giving an old laptop to a friend who had his laptop stolen and instead of moldy old swiss cheese Win7 I put a clean copy of win10 on it. A new battery from Walmart and an SSD drive, the old Lenovo thinkpad T500 is faster than my video editing station. 🙂

Mine came in a double envelope, with the authentication/activation number on the inside envelope. You need to scrape the silver color off of the sticker over the license number (I wouldn’t try pulling the silver sticker off – it’s a clear sticker with the silver stuff you can remove with your fingernail or a coin on one side. Once you remove that, it’s like it’s not even there. Installed quickly, activated properly, and works as Windows 10 should!

    Perfect timing

    Time to upgrade one of my desktops to Windows 10. Found this listing and seen it had taken a fairly descent price drop so the bells went off and signaled now would be a good time to purchase a pro version. Will be doing the upgrade this next week.

    Actual legit and usable software in hours from a trusted vendor with cjkeymall protection!

    I ordered this at lunch via the cjkeymall app. The email with all the information I needed was waiting for me when I got home. All the links and license key was included. I downloaded the .iso and the media creator tool and was off to the races!Actual legit and usable software in hours. Create you own hard media at home if you want it.

    Works on reloading my home system

    Did what it was supposed to do. I had originally installed windows 7 then upgraded to 8 then 10. When the system failed I could no recover from any of the recovery media I had so I had to format and start over. Has worked great since then.

    Installed in 5 minutes on my new build. I have read a lot of negative reviews on W10 but I like it. I’m not sure what the problem with every one not liking it but we don’t have a say it as far as I see it.

    Loaded very well with no issues.

    Going from Win 7 PRO to Win 10 PRO is a big change for us. Activation and Updates were done when we checked. We are pleased with this product.

    Best operating system ever. Microsoft is finally going in the right direction. All the others are okay but this one is great.

  184. Eric Barnhizer

    It’s all good!

    After my old hard drives failed, I decided to replace the upgrade version of W10 [ upgraded over W7.] with this clean install of W10 Pro. Now that my system is back to being fully restored, I have noticed a significant improvement in performance and stability. There were no issues with the installation or registration of this software. The OS has a very good set of utilities for setting up most of the hardware. My computer is a 2011 X58 based system, and I was able to install 2 new SSD’s and get everything running at peak performance with ease.

    Good cheap price. No diference to full retail model but apparently there is no microsoft support, but doesn’t matter because you can find whatever help you need on the internet from any number of help forums.

    Easy to install even without a disk drive.

    Installed and activated seamlessly. If I had not had a disk drive, then I could have downloaded the file from Microsoft and put it on a USB.The Toshiba I installed this on had to have some BIOS settings changed before I could boot it from the disk drive, so pay attention to that when installing. I like the fact that this comes with a sticker to place on the machine giving the product key and COA. As an administrator, this makes it easy to keep a log of what keys are assigned to what laptops since we allow BYOD where I work, but have to have a professional edition of Windows in order to link up to the domain and ethically install software that we have licenses for. Keeping this record makes it easy when something goes wrong and Windows needs refreshed, reinstalled, or just a driver needs updated.Seamless installation, and convenience of using the included disk or downloading from the internet. Windows has its weaknesses, but this disk is a great product.

  188. Eeerock

    Double sealed. scratch-off perfect. No problems at all. Activated, updated.

    Double sealed. scratch-off perfect. No problems at all. Activated, updated. Not sure why others had issues, probably because it HAS to be on a NEW install, blank hard-drive, NOT an upgrade, or reload….

    Must have a disk

    I found out the hard way, “If you have a boot problem you must have the Win 10 Install disk”. I did a free simple un grade from MS, from an older 8.1. No install disk. It crapped out and could not fix without it. Seems a rip.

    Worked as intended. First change the key to default pro key. You can find this with an Internet search. Then windows upgrades and you activate with your new key. Simple as that. Thanks!

    Great deal on the Pro version, … since you’ll be forced to run WIN 10 eventually

    OK, so I HATE WIndows 10, but this is a Great Deal for Prime members to get the Pro version.I’m not positive about this, but I read that the Microsoft Overlords don’t force updates on the Professional version. Most of my PCs have the free upgrade with the Home version which is really, really terrible. They act like a company’s IT department, but controlling your personal assets; taking over your computer, regardless of what you’re actually doing and even restarting at their whim.

    It’s windows…..what else do you need.

    Some people have complained about how the packaging doesn’t look “OFFICIAL”.This is an OEM System Builder. They don’t bother with fancy packaging or cases since a customer will never see it.It’s got a Windows 10 disc. The product key works. Perfect.

    It will restore your faith in MSFT

    So much better than Win8! Win 8 had me convinced MSFT was intentionally trying to go out of business. I was actively looking for alternate OS but this has definitely restored my faith in MSFT

    Only issue was a Microsoft problem. The Disk would only install Windows 10 Home. I had to call Microsoft. The computer did have the digital license. They seemed familiar with the issue and had me put in the default product key for Windows 10 Pro and then have it update. Worked fine when we did that but I spent a lot of time burning .iso files, etc… thinking there was something wrong with the disk.

  199. Joseph S.

    No issues

    I can give a unabashadly positive review to this inexpensive way to upgrade from Home Edition to Professional. There are complications however if you previously upgraded your machine from Windows 7, Windows 8, or Windows 8.1 Home Edition to Windows 10 Home Edition. You must go through the following step-by-step operation in order to successfully upgrade your Windows 10 Home Edition to Windows 10 Professional….1) My computer originally had Windows 8.1 Home Edition installed on it. I upgraded it to Windows 10 Home Edition in January, 2016. The Activation Type was “Digital Entitlement” which means that Microsoft Update performed the upgrade from Windows 8.1 Home Edition to Windows 10 Home Edition. This “Digital Entitlement” is probably what complicated the upgrade using the Softkey Product Key.2) In order to upgrade using Softkey’s Product Key in this situation, you must perform the following steps: a) Select the button and go to Settings->Update & Security->Activation b) Select the button and enter the following “Default” Product Key — DO NOT ENTER THE SOFTKEY PRODUCT KEY AT THIS TIME!!! VK7JG-NPHTM-C97JM-9MPGT-3V66T c) The upgrade from Windows 10 Home to Windows 10 Professional will now successfully complete and the computer will reboot a couple of times. d) Once the upgrade process from Home to Professional is complete, Windows 10 Professional will run, but will not be activated. e) To activate using the Softkey Product Key, Select the button and go to Settings->Update & Security->Activation f) Select the button and enter the Softkey-supplied Product Key. Windows 10 Professional will now activate and everything will work.

    Works as it should!

    WIN 10, I hate it but my new build requires it so I’m stuck having to learn it.

  204. Doctor Love


    You have to forgive my suspicious nature, but for less than $12.00 it was worth a try for an upgrade from Windows 10 Home to Windows 10 Pro. However, I wasn’t going to take a chance of using someone else’s App to install Windows 10 Pro on my machine IF I didn’t have to; who knows what Trojan Horses (viruses) could be installed on your machine. So when the email came with the “Digital Serial Number” and other instructions, I simply chose to allow Microsoft to verify the upgrade number; On the first try I got a feedback message from Microsoft that it wasn’t a verifiable product code (because it wasn’t), but I tried again and (Much To My Relief) Microsoft accepted it as a “Digital Key Code” and it went through and was upgraded by Microsoft itself. You can’t ask for more than that, and I didn’t have to run the risk of having somebody install their own App on my machine ! I’m NOT saying they would, but why take the chance, besides the Digital Key Code was Verified by Microsoft ! 

  205. Jennifer Chapman

    Get the one directly from cjkeymall, don’t risk the market sellers.

    If you get a legit copy, it’s good. Also, for those having problems with the MS sticker over the CD-Key, don’t try and peel it off, very softly scratch it off like a lottery ticket. This is to protect your CD Key from getting snagged during the shipping I imasgine.

  206. Andrew Sears

    Legitimate Product!

    Bought this for my friend’s computer build. This is seriously legit. Ignore the weird delivery date; this is just the key. Seller sent key via their cjkeymall marketplace email within 24hrs, No issues activating Windows.

    Everything was Beautiful and in order

    Everything was Beautiful and in order. It was an Original OEM version of Windows 10 Pro. Yes the Disk did have the embossed wording ( MAID IN Puerto Rico ) Nice to see Microsoft supportive in different regions. P.s this Bought version supported all my hardware vs the free version I downloaded as a free upgrade from my paid OEM version of Windows 8pro 😲

  210. Garr Godfrey

    Legit from, small activation code print

    Windows 10 is ok. an upgrade from 8.1. Only buy this if the seller is, and if you pay much less than $100 don’t expect it to be legit.The activation code is very, very small and it is under a “scratch off” portion on the COA label. Don’t be confused by the part that says “this is not a coa”. That is the sticker that surrounds the COA. I need a magnifying glass (or use iphone camera and zoom) to read the letters.

  211. PM

    Installed without a hiccup.

    After assembling my computer, I slip the disk into the CD/DVD and followed the instructions. Several minutes later my computer was up and running. That is all there was to it. Note: Carefully rub off the silver film that is covering the Key Code. I gently used my nail to remove cover.

    Windows 10 Pro: Awesome Price & Professionalism

    Microsoft Windows 10 Pro 64 Bit System Builder OEM | PC Disc

     An awesome price and the latest Windows 10 Pro 64-Bit System Builder OEM, I’m sure your purchase will be satisfying. You will display more professionalism with this product.Additionally by now, I do have to say that the drivers for the latest graphic cards/GPU are very broken on Windows 10. That becomes my only disliking but we must give Microsoft time, don’t hit the dislike button because you hate Microsoft or have impatience to updates.

    I wasnt sure at first about whether to build my new edit system with Windows 7 or Windows 10. I had tried Windows 8 and HATED it. Windows 10 has combined the stiff I DID like about Win8 and the stuff I love from WIN7. And it boots FAAAAAAAAAAAAST!

  214. not a geek

    Good for backup.

    Well, it didn’t install on my machine because of a clone SDD. The boot sector is on the original drive. I’m sure it will be good on a fresh install. I have way too much on the computer to try a clean install.

    From disappointed to Ecstatic in a few hours. Well Done. Great Service

    Update to previous 1 star review. Contacted seller. He responded promptly and sent me new code that worked perfectly to upgrade my windows 10 home to pro. Worked perfectly. Fantastic experience. Highly recommend.The key arrived promptly after purchase! I was excited to get started. I purchased it after reading in the Q/A that it could be used to update windows home 10 to pro. I have been at if for 2 hours trying to find a work around but the key will not work. I purchased the key today but it will not work to upgrade windows home edition and the link provided in these Q/A will not provide an iso. I have sent a message to the seller band will remain optimistic that they will reply with a solution, however the KEY is Useless so far.

    Best Windows yet

    Best operating system ever. I thought Windows 7 was the best till I installed this. Have been using Windows 10 for about 4 months now and had to buy this for a clean install.

    Good price; Activated a USB key install just fine. There are some exceptions for what it will activate. The seller will advise. Mine came over email with in 24 hours but they also mail a hard copy sticker thingy for you files or to apply to the customer’s device. 

  223. Judgemhc

    Great Product, Just as Advertised

    I needed a new License Key to remedy an activation problem with my 64-bit version of Microsoft Windows 10 Professional. After contacting the Seller and receiving an almost immediate response, indicating the Key is genuine, would work, and would not expire, I purchased it. It worked as hoped and may be the best investment I make this entire year. Thanks! 

  224. Gramps

    Product key number for windows 10

    This was for a product key number only, not an hard copy of Win10 Pro. I received the number via email just shortly after I bought it via Paypal.It worked like a charm. This not a small thing as there is a lot fraud websites out there scamming people and that is not happening with this seller. Would deal with this seller again.

    Genuine OEM

    This is not a review of Microsoft Windows 10 Pro 64-bit OEM DVD itself, but an acknowledgement that the OEM package I received from cjkeymall is genuine in that it correctly matches all of the points Microsoft directs one to look for. Also, the scratch-off that covered the product key scratched off just fine, although I used a dime instead of my fingernail.

    Great OS!

    Got this before I knew about the Media Installer you can download fromm MSFT. I had wanted a clean install of Windows 10. Either way, I am very impressed with the agility of Windows 10 and its functionality. I love the new Edge Explorer… way faster than Chrome and much more secure, plus it seems to be able to use those annoying sites that used to be ‘Chrome’ specific.

She never really liked windows 7 and it had become slow and always seemed to update each time she got on it. I had the hard drive replaced with a SSD and Windows 10 64 bit OEM and she loves it. I like it as well and plan on upgrading my Windows 8.1 sometime soon.
