All reviews of Windows 10 Professional 32 64 Bit Retail Key
  • ZN

    Excellent service. Received my key to Win10 Pro (Retail) within a minute by email. Worked like a charm!

  • These guys are the real deal. Had an issue with the code, they responded within 10 minutes, and continued to do so until the problem was resolved. It was a very pleasant expirience!

  • Indeed. I purchased the license and got it within 45 seconds. The email comes with an image/photo of your license and instructions for activating. Unlike others here, I had no issue with messages stating that it had already been used. I was literally activated within 5 minutes of coming to this site. I was also very skeptical as the price is 1/20 of what it cost from the MS store. Thanks EF.COM!

  • First the key did not work with error “product key is being used on another computer”. However support reacted fast I got replacement key on the same day.

  • I bought this key, and I got it in a few minutes. What’s great about this product is that they weren’t lying about the fact that it’s retail! I typed in slmgr /dli in command prompt, and it says it’s retail! I recommend this seller!

  • bought another windows pro 10 key for my sons pc.
    delivered in less than 2 minutes.
    my son did exactly the same as me in my review above or below…
    HOWEVER it said the product key had been activated on another computer.
    OMG my son being 15 started effin n jeffin that id broke his pc as Windows wasnt activated………
    emailed customer service with the product key we had bought and a screenshot of his error upon trying to activate.
    seller replied within 10 minutes and troubleshooted with us. THE PRODUCT KEY WAS GOOD all we had to do WAS PHONE A FREE NUMBER 5 minutes later activated windows 10pro.

    sorry about the caps lock, i just wanted it to be seen that if your pc says that the activation code has already been used on another pc……its very likely just a quick 10 minute fix.

    thank you Electronic First.com

  • Bought the windows 10 pro key/ delivered in less than 2 minutes.
    I already had windows 10 home installed.
    I went to settings /update and security /activation in the left panel of windows / change product key. I entered the key and my system threw an error unable to upgrade your edition ( 0x80070005) BUT I Restarted my pc and hey presto Windows 10 pro.
    To check that you have successfully upgraded to 10pro press the Windows key and R / type winver in the box press ok and you will be presented with a box saying Windows 10 pro.

    Excellent site will recommend.

    Only downside is I couldn’t place an order from my mobile device, but my pc worked fine

  • Was initially skeptical due to the very low price, but the email response was very quick with the License Key. Only took about 5 minutes for me to get the email with the license key in it. Would highly recommend getting the key. It is a Retail key, and verified with the following command in cmd: slmgr /dli.

  • Excellent customer support. After receiving a key for windows 10 pro. The key did not work. Contacting support they gave me another key instantly which worked.

  • The first key they sent me was not working but then I contacted them and they sent another code and it worked. I am very happy. They respond in less than 20 minutes

  • Very Happy with my windows 10 Pro. Was delivered quickly and installed without any glitches…and so far so good.
    Will definitely be back again for more software in the future.
    Many Thanks

  • I downloaded the version of windows 10 suggested onto a usb boot drive. The installation was very easy. I am very pleased with my purchase.

  • Exactly what I paid for, nearly instant delivery right to my inbox.

    PC building on a budget and found this site for my OS, (Win 10 Pro)

  • Bought Windows 10 Key, First Key didn’t work, because it was “already in use”. After a complaint, got a new key within 5 minutes, then it worked.

  • Very straightforward, received the license key and it activated windows immediately. And here I was thinking I’d have to pay microsoft £200!

  • Like many mentioned it below, I was no sure if it would work or not. But yes, worked quite well. Transactions are via PayPal, so seems entirely secure. The delivery is relatively quick and within minutes. I used it to activate my Win10 pro and the license was activated right away and locked to my PC hardware. The license is not transferable, which is fine with me, considering the price. Happy to buy again and highly recommend.

  • I had good experience with the company. Purchased Windows 10 retail key and it works for me, additional steps of activation were required though but support team helped me quickly and responsively!

  • My Windows 10 Education version had been giving me a lot of BSODs, so I wanted to try a different version. I was honestly very hesitant to try because of the low price, but it worked perfectly! You can trust them.

  • I ordered a online product as it was one of the cheapest around.

    Fast email response and very happy with product it far excels what I was expecting.

  • The low price made me hesitate, but for $10, what did I have to lose. The key arrived in a very short time. I deleted one of my Ubuntu flash drives and used it for the Windows download. I’ve installed Windows hundreds of time at work and this was as smooth as any of them. I will probably buy one or two more.

  • I’ve purchased two win 10 key codes from here and both worked great. One home version and one pro. Would buy from again without a second thought. They saved me a good amount of money and sent me a key code in just a couple minutes. Couldn’t be happier.

  • Good price and prompt service. The digital product arrived almost immediately. I actually bought a second one!


  • This is the easiest installation of software I have ever experienced. The service is super-fast, and the installation is flawless. If you’re buying multiple titles, the shopping cart is a little hinky – you have to buy one title at a time, or at least, that was my experience. I have been back several times, and will be back many more times!

  • Excellent service. Bought 2 items in seperate transactions and both received within 5 min or purchasing.

    Will definitely use again. 5 🌟

  • I bought windows 10 pro and ms office together. retail is over $200. Price here was less than $50 for both! When the deal is too good to be true… well in this case it’s just TRUE. Great pricing, easy process, great instructions.

  • I have had a watermark on my PC for a very long time and sought to get rid of it cheaply. I could not believe the discounted price of £7 and thought it was a scam.

    Brought it figuring that if it was I would only be losing £7, but to my pleasant surprise it worked like a charm and upgraded my edition of Windows 10 from Home to Pro; finally removing that pesky watermark.

    10/10. Would recommend.

  • Sam

    I was very skeptical about buying this key, but just as another has commented: this is a retail key and not OEM which means that it can actually upgrade Windows 10 Home to Pro, just worked for me. Just ignore the default OEM description.

  • Key arrived in minutes. Regardless of what the description says, you CAN use the key to upgrade Windows 10 Home to Pro. Simply go to settings->Update and Security->Activation->Change product key.
    Enter the key sent. Windows will install the extra features and reboot a couple of times. None of your settings or programs will be lost.
    Note, once updated you may need to do the change product key part again and enter the key again to activate windows. Once I did this everything was fine.
    Highly recommended for anyone wanting features such as drive encryption and remote desktop etc.

  • MP

    Ive bought cheap windows before but was surprised you can get the oem version for pess then 3€ and not get conned. Instant delivery. Working fine. Really satisfied!!!
