Windows 10 Embedded Product Key Tool

Last updated by

Product Key ToolWe’re proud to introduce the immediate release of our newest utility for Windows users: the NeoSmart Technologies Embedded Product Key Tool. Designed for users of Windows 7, Windows 8, and Windows 10, our embedded product key tool will retrieve and display the Windows setup product key embedded in the BIOS or EFI, allowing you to store it for safe-keeping or use it to reinstall Windows with an official Windows setup image.

Are you having trouble with your Windows?
Before you reinstall, have you considered using a custom boot repair CD that might be able to save you the hassle of a format and reinstall? Easy Recovery Essentials for Windows can fix your non-booting PC with just one click, without losing any of your data!

Ever since Windows 8, PCs and laptops no longer ship with the Windows Certificate of Authenticity (COA) that we’ve all become accustomed to seeing:

COA Certificate of Authenticity

So how do you install Windows without a product key? Well, these days a product key unique to your machine (or, in some cases, to your manufacturer or make/model) is embedded into the BIOS or EFI, basically programmed into the computer itself. This prevents problems with the COA being rendered illegible, making situations like this a thing of the past:

Unreadable COA

However, the real reason computers and laptops no longer ship with COAs is because the manufacturers complained to Microsoft that having to affix a customized sticker to each and every PC or laptop they manufacture was a real (and expensive) pain in the royal you-know-what, and begged and pleaded for another option. It’s simple economics, the more-easily you can mass-produce a product with as little variations as possible, the cheaper and faster it is to make it. Microsoft capitulated, and the rest, as they say, is history.

This embedded product key is not wiped when you format or reinstall, or when you replace your hard disk – it’s stored in the NVRAM of the BIOS/EFI on the motherboard itself. Depending on what version of the Windows setup image you’re using, it might be able to retrieve the key for itself – in which case you’ll never be prompted to enter your key. It’ll just directly read the programmed code from the BIOS and continue on its merry way. However, if you’re trying to install Windows 7, Windows 8, or Windows 10 and you don’t have a COA because your manufacturer is using an embedded product key but your setup image doesn’t support it, or if you’re trying to retrieve your key for safe-keeping or other purposes, our product key tool will retrieve and display it for you, without even a single click:

So the next time you go crawling under the desk looking for a product key to copy down (or snap a photo of), don’t worry too much when you don’t find one: just download our product key utility (it’s free!) and use it to get a copy of your embedded product key.

    2. I’m trying to put a craft disc onto my new laptop and it’s asking for a key tool no could you please help I’ve just bought my laptop and its Windows 10 thank you x

    4. Is there any way you can add some command line options to this tool, so it will write the key to a file or something like that?

    6. is there any capability to run this tool in a cmd or powershell script in order to obtain the serial and for example, use it to automatically activate during image deployment?

      Thanks for the great tool!

    7. I can’t get the system to work, it always freezes up on me during the process, now my windows does not work properly due to not being able to get product key.

    8. Will this tool detect system builder OEM keys or just manufacturer OEM KEYS EMBEDDED IN BIOS.?
      Does it pick up Retaill keys too or just OEM?

      Thanks!

    11. Hello. Great tool i use it all the time. I would also love a command line version to output the key to script a re-activation. Or better yet, if the program could input the key and activate windows automatically that would be excellent!. Cheers. Aaron

    13. Great Post. I will like to do the opposite. Inject Windows Key in my BIOS. Please how do I do that? Thanks.

    16. Command Prompt Admin Mode:
      powershell “(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey”

    19. so how do remove the embedded windows key as I’m on windows 10 home an want to do a fresh install of windows 10 pro but because the key is embedded it keeps reinstalling home all the time witch is not what I want

    20. It would be great, if you could make a command line parameter, so that the key could be written in a text file.

      for example like this:
      Oemkey.exe /outputkey > %temp%/key.txt

      (so that only the UAC opens, but after that no new windows containing key; the key should then be exported to key.txt)

    22. Hola mi surface al encender me sale un candado rojo y después me pide password de uefi y no la se al tratar 3 intentos me manda a una venta blanca que solo da un información de la surface pro 4

    23. I couldn’t get any help by this. It Showed me message like-Unable to open MSDM table!

      This PC does not contain an embedded product key – search for a product key sticker or contact your manufacturer for assistance.

      What do I do now? help.

    24. @sneha: the message is pretty clear. Your PC does not have an embedded product key. If it’s a genuine installation, you’ll have a product key sticker somewhere on the machine.

    26. Hi Marcos
      I have dual booted windows 10 with Ubuntu 16.04. Later my hard-disk crashed and I had to replace it. Now I have only Ubuntu 16.04 on my system. Can I boot windows again and retrieve the product key using the software? If so that would be great relief. Please help me out with this.

    28. Don’t bother. Microsoft are money hungry bastards. There are many tools online you can use to replace these silly things. Besides, I have upgraded and I can say this. You are not missing out on anything. Just a few unimportant things and the rest is just like the older version. Not worth the upgrade.

    30. pls I need product key for my window 10 , its showing me my window license will soon expire, I need product key pls

    31. Doesn’t one’s copy of Win10 (e.g., from a download) have to have the same Product Key Number as the embedded one, which your program extracts?

    35. thanks to you I retrieved my product key but my windows fails to recognize it, what do I do?

    37. Does this tool provide a command line option for writing keys to a text file without showing the GUI? Thanks! Chris

    38. Is there a way to remove or change the key embedded in the UEFI? My laptop came with Win10 Home, but I want to replace the embedded key with my Win10 Pro. key…

    39. I am a no-no when it comes to computers, I was browsing the net in the hope that I could find something to help me and bingo.
      I am yetc to try out your suggestions but just reading and watching the video it looks like I have found heaven.
      Thank you so much.
      Jim.

    40. the programme does not work. I tried but it does not make any difference. i don’t know if ever the problem is caused because i added additional feature key to my windows 8.1 pro build with bing to pro build in 9600. please help me please…… i need to upgrade my windows to windows 10, so it requires to activate the current windows to proceed.

    41. I am also having this issue. It asked me once if I want to install more Windows features…but I guess it updated to some trial version and now it keeps popping up in the middle of everything and says “Activate Windows”. I can’t get rid of it and the computer.notebook I have is a Windows 8.1 Pro ..Builders something/ Could anyone please help me get rid of this message? I cannot afford the new Windows OS it is trying to sell me……I just want my 8.1back. Thank you!

    42. This is an amazing new idea,i thought I was in big trouble when I bought my laptop and discovered it had no product key. So I am wondering what I was going to do not being able to activate windows! Then a total genious came up with OEM Product key tool. Thanks so much Neo Smart.

    44. It did not work. I bought this PC from Amazon &it has Win10 Preinstalled. Is there another way to get my key code?

    45. Really? Most oems never used the attached sticker COAs key. How is adding a COA with a unique number any harder then adding a unique s/n?
      Theft and reusage!

    46. Great to have the key but I can’t even get to that part. Microsoft did a critical update without me knowing about it.I have been in turmoil ever since. That was the middle of Sept. Working at home, no computer, my nerves are shot. Is that the big plan? A life changing Pandemic and just as you get adjusted and feel like you’ll be okay, resources cut off little by little..

      Const KeyOffset = 52
      i = 28
      Chars = “BCDFGHJKMPQRTVWXY2346789”
      Do
      Cur = 0
      x = 14
      Do
      Cur = Cur * 256
      Cur = Key(x + KeyOffset) + Cur
      Key(x + KeyOffset) = (Cur \ 24) And 255
      Cur = Cur Mod 24
      x = x -1
      Loop While x >= 0
      i = i -1
      KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
      If (((29 – i) Mod 6) = 0) And (i -1) Then
      i = i -1
      KeyOutput = “-” & KeyOutput
      End If
