How to view your product key in Windows 10, Windows 8 and Windows 7

RЕCOMMENDED: Click here to fix Windоws issues and optimize system performance

If you lost or forgot where you had stored your Windows product key, I have a solution for you. Today we will see how a simple VBS script can be used to show us the product key of an installed copy of Windows 10, Windows 8 or Windows 7. It is a simple solution to extract your product key from the OS installed on your PC without using any third party software. Here we go.

Actually, earlier I posted a similar solution which used PowerShell. but many users complained that it fails for them. PowerShell might require additional user skills and extra tweaks to run unsigned cmdlets.

Compared to PowerShell, this VBScript solution is almost perfect. All you need to do is to just click the file. To view your Windows 10 product key

  1. Open Notepad.
  2. Copy and paste the following text into the Notepad window
    Option Explicit  
 
Dim objshell,path,DigitalID, Result  
Set objshell = CreateObject("WScript.Shell") 
'Set registry key path 
Path = "HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\" 
'Registry key value 
DigitalID = objshell.RegRead(Path & "DigitalProductId") 
Dim ProductName,ProductID,ProductKey,ProductData 
'Get ProductName, ProductID, ProductKey 
ProductName = "Product Name: " & objshell.RegRead(Path & "ProductName") 
ProductID = "Product ID: " & objshell.RegRead(Path & "ProductID") 
ProductKey = "Installed Key: " & ConvertToKey(DigitalID)  
ProductData = ProductName  & vbNewLine & ProductID  & vbNewLine & ProductKey 
'Show messbox if save to a file  
If vbYes = MsgBox(ProductData  & vblf & vblf & "Save to a file?", vbYesNo + vbQuestion, "BackUp Windows Key Information") then 
   Save ProductData  
End If 
 
 
 
'Convert binary to chars 
Function ConvertToKey(Key) 
    Const KeyOffset = 52 
    Dim isWin8, Maps, i, j, Current, KeyOutput, Last, keypart1, insert 
    'Check if OS is Windows 8 
    isWin8 = (Key(66) \ 6) And 1 
    Key(66) = (Key(66) And &HF7) Or ((isWin8 And 2) * 4) 
    i = 24 
    Maps = "BCDFGHJKMPQRTVWXY2346789" 
    Do 
           Current= 0 
        j = 14 
        Do 
           Current = Current* 256 
           Current = Key(j + KeyOffset) + Current 
           Key(j + KeyOffset) = (Current \ 24) 
           Current=Current Mod 24 
            j = j -1 
        Loop While j >= 0 
        i = i -1 
        KeyOutput = Mid(Maps,Current+ 1, 1) & KeyOutput 
        Last = Current 
    Loop While i >= 0  
     
    If (isWin8 = 1) Then 
        keypart1 = Mid(KeyOutput, 2, Last) 
        insert = "N" 
        KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0) 
        If Last = 0 Then KeyOutput = insert & KeyOutput 
    End If     
     
 
    ConvertToKey = Mid(KeyOutput, 1, 5) & "-" & Mid(KeyOutput, 6, 5) & "-" & Mid(KeyOutput, 11, 5) & "-" & Mid(KeyOutput, 16, 5) & "-" & Mid(KeyOutput, 21, 5) 
    
     
End Function 
'Save data to a file 
Function Save(Data) 
    Dim fso, fName, txt,objshell,UserName 
    Set objshell = CreateObject("wscript.shell") 
    'Get current user name  
    UserName = objshell.ExpandEnvironmentStrings("%UserName%")  
    'Create a text file on desktop  
    fName = "C:\Users\" & UserName & "\Desktop\WindowsKeyInfo.txt" 
    Set fso = CreateObject("Scripting.FileSystemObject") 
    Set txt = fso.CreateTextFile(fName) 
    txt.Writeline Data 
    txt.Close 
End Function
  3. Save the text above to a file with the ".vbs" extension on the Desktop.
    Bonus tip: To make sure that you saving the file correctly with the ".vbs" extension, you can type its name enclosed in double quotes, for example, "BackupWindowsKey.vbs".
    backup windows product key Windows 10
  4. Now open your BackupWindowsKey.vbs file
  5. Voila, you product key is displayed on the screen!
    show Windows 10 product key

Click here to download the BackupWindowsKey.vbs file

I tested this trick on Windows 7, Windows 8 and Windows 10. It works flawlessly in all mentioned operating systems. Credits: nononsence @ MDL.

      1. Hi Sergey,
        can this script find product key on external drive with windows 8, and 8.1 64 bit installation connected on windows 10 64 bit laptop?
        produkey program could not find the product key using option “load product keys of external windows installations from all disk plugged to your computer

        can you please twick the script so I can find the product key on my windows 8 laptop that is not working?
        I tried few other programs but no avail.
        by the way great script. I am not programmer.
        thank you.

        1. The script works in the loaded OS only.
          I would suggest you the produkey app, but you have already tried it.
          Maybe your laptop has some different kind of license, e,g, the key is flashed into UEFI bios, that’s why apps fail to retrieve it.

    3. I’m in charge of license management at the small IT company I work for. I cannot tell you what a gem you have just provided now that Windows 10 reinstalls are starting to happen thanks to some users. No longer have to worry about productkey64 or anything else. Very nice work, today you win the internet!

    2. Change “DigitalID = objshell.RegRead(Path & “DigitalProductId”)” to “DigitalID = objshell.RegRead(Path & “DigitalProductId4″)” for Enterprise

      3. Mateusz Paluszkiewicz, I changed “DigitalProductId” to “DigitalProductId4” on Sergey Tkachenko’s VBScript for my Windows 7 Professional … and I got my Product Key. I could not believe my eyes, but there it was right on front of me, after years of frustration. Thank you. Thank you. Thank you very much.

  4. I tried it on six machines. On four (2-Win 8.1 (a laptop and a desktop), 1-Win 7 (laptop), and 1-Vista(desktop)) it worked correctly. On the other two (1-Win 8.1 and 1-Win 8 — both laptops), I received this error message:

    “Unable to open registry key ‘HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId’ for reading.”

    The registry entry does exist — viewing with Regedit.

  8. Got error because my username is only part of user account foldername (has .%userdomain% attached),
    used userprofile setting instead of username, should also help people with more than 1 windows e.g.

  10. I don’t quite understand this part of the script:


    keypart1 = Mid(KeyOutput, 2, Last)
    insert = "N"
    KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0)
    If Last = 0 Then KeyOutput = insert & KeyOutput

    Could you please describe how it works? How is the ‘N’ placed at the correct place? And if my product key doesn’t have a ‘N’, will it still work correctly?

    Also, I’ve found out by testing that a Windows 10 key also can consist of a ‘5’. Does the script need to be extended for that purpose?

    Thanks,

    1. Perhaps try this on windows 10 as admin:

      wmic path softwarelicensingservice get OA3xOriginalProductKey

      Or run this vbscript:

      Set WshShell = CreateObject(“WScript.Shell”)
      MsgBox ConvertToKey(WshShell.RegRead(“HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId”))

      Function ConvertToKey(Key)
      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
      Loop While i >= 0
      ConvertToKey = KeyOutput
      End Function

      I get different results from this vbscript. But when I run the one in the blog post above, it gives me the same key as “wmic path softwarelicensingservice get OA3xOriginalProductKey”

  13. Hey with this script i can read the Key from Win10Pro but the Key is on all Computer i have seen the same Key this detected Key (VK7JG-NPHTM-C97JM-9MPGT-3V66T) is a generic Key and it is useful for install Windows 10 clean but for Activation is this Key not possible.
    I have read an other a different key in my System with “Token Restore” v. 2.2 for Win7 and the same key i have read with ProduKey.exe (2011version) and keyfinder.exe ( from 2009) but i dont have try this Key for Activate while my Win10Pro is 100% activated directly after Upgrade from Win8.1Pro

  14. I found that it worked fine on my Windows 10 desktop. However a simpler way to get the same result is to use Belarc Advisor. This gives all manner of information, including all software codes.

    1. I am not sold 100% on Belarc, it only pulls Operating System and Office Suite Keys 50% of the time.

      I will try this out on Operating Systems and see how it fairs.

  16. Thanks for sharing. I have a try on a notebook with Windows version Vista Business. It is strange that the key reproduced is a bit different from the one I input on activation (which is printed on the bottom on my mechine).

    Reply

  20. if u want to check windows 10 home edition key will work or not, just go to notification, then windows update, then activation. type the key shown by your pc, if u got message to activate then that product key will work.
    & Thanks for that code. :)

  22. This could be improved a bit by allowing the user to select where to save the info via:

    http://www.robvanderwoude.com/vbstech_ui_fileopen.php

    As it stands, the script gives me permission errors when trying to save to the folder you specify since C:\Users isn’t always the home directory for a user.

  24. Hello,
    Here I have the full code to view any windows key also the ones they put in the bios.
    It’s written in Visual Basic 2008, but you maybe can transform it in later versions.
    Here we go:
    Create a form with 2 textboxes called Textbox1 & Textbox2
    One Exitbutton called Button1
    The paste in following code:

    Public Class Form1

      The original one also works but it get a message when I whant to print the result.

  39. Wow it worked great. Thank you for providing this method, but I have a problem here. When I check in Setting/Update & security/Activation, it shows my product key : XXXXX-XXXXX-XXXXX-XXXXX-ABCEF (well it’s not my real product key but something like that with the last 5 characters are shown). And when I run your script, it shows me a key THGFE-TFNDH-4HFTD-FHRT6-SHFGD (it’s not my real key too). But my point is do those 2 keys suppose to have the same last 5 characters ? In my case, they are different. Is that normal ? If I reinstall windows 10, still I can use the key your script gave me to reactive windows ?

    Reply

    2. If you got Win10 as a free upgrade then any key you retrieve will be useless because it is totally generic. That is, all free Win10 Home upgraders have the same key, and similarly free Win10 Pro upgraders have the same key.

      Win10 stores your hardware info on MS’ servers so whenever you want to reinstall just skip the key and it will automatically reactivate after connecting to the net and comparing your current hardware info with the stored value. (You can actually change your hard disk and most other things but if you change your motherboard with another model then the activation will fail.)

  40. Hi all, here is the simplest solution:

    press windows key, type in “product key”, the results will show you option under settings: “change your windows product key”

    Click that option.
    Then scroll down & get your last 5 characters of your key, copy this or write it down.

    then press windows key & type : “regedit”

    registry will open, now press cntrl+f to search registry.

    Type in your 5 keys obtained earlier here, then press find…Then Volia…your key will be displayed on right side of screen. (25 Characters long)

    Thats it…eezi peezi… :-) ;-)

  41. Why does my partial product key (last 5 characters) that is shown under Windows 10 Settings not match at all with what this tool shows me ?

    Also, what is the key that is shown in the registry under “BackupProductKeyDefault” in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform ?

  44. There seems to be something wrong with the vbs script posted on the winaero site:
    https://winaero.com/blog/how-to-view-your-product-key-in-windows-10-windows-8-and-windows-7/

    I have tried this script on several win7 PCs, and the key it displays does not agree with the key shown by other similar utilities such as WinKeyFinder or MagicJellyBean.

    The following all display the same key:
    http://www.winkeyfinder.com/download/winkeyfinder-download/download-win-keyfinder-2-0-beta-1.php
    https://www.magicaljellybean.com/keyfinder/
    http://www.howtogeek.com/206329/how-to-find-your-lost-windows-or-office-product-keys/

    Either your script has a bug or all these other utilities are wrong. The last one on the list is also a similar vbs script, although shorter than the one on your site.

    1. …also the win7 keys produced by your script are invalid according to the Ultimate PID Checker:
      http://janek2012.eu/ultimate-pid-checker/

      1. Thank you very much.
        It was a bug in the script.
        The missing part was as follows

        If (isWin8 = 1) Then 
        keypart1 = Mid(KeyOutput, 2, Last) 
        insert = "N" 
        KeyOutput = Replace(KeyOutput, keypart1, keypart1 & insert, 2, 1, 0) 
        If Last = 0 Then KeyOutput = insert & KeyOutput 
    End If

        I corrected it, now it works fine.

  45. I remember seeing this same VBS a long time back on another site where the original poster had figured out the decryption algo. Forget which one now… But in any case you should credit the original source you took it from.

    Reply

    1. OK, do you remember the original author?
      Try to google it. Many web sites keep posting the script without credits. Hard to find the original author.
      —
      Actually, I have this script for ages in my collection of scripts and just do not remember where I grabbed it.
      It was several years ago.
      Just as much as I want to credit original author, I don’t want to credit the WRONG PERSON as author.

  49. I have my user folders on another drive, so the save feature didn’t work at all.

    After a little searching, and banging my head against the keyboard repeatedly (I’ve never touched VBScript before), I was able to merge your script and some code from a forum to 1) remove the user name and profile search entirely, and 2) get the script to save the file to my desktop, even though my user profile is on a secondary physical drive.

    I’m testing on Windows 7, and can’t quickly test it on 8 or 10.

    Here’s the modified script:

      1. I think I’ve built in a test for Enterprise, based on the info from Mateusz and some Googling about how to test if a reg entry exists.

        Show/Hide

        Reply

          1. Tried to clean it up a bit and stick closer to the original style. Updated the check for Enterprise so it makes more sense when simply reading it. I’m only posting that section this time, as nothing else was changed.

            'Registry key value
            DigitalID = objshell.RegRead(Path & "DigitalProductId")
            Dim ProductName, ProductID, ProductKey, ProductData, Enterprise
            'Get ProductName, ProductID, ProductKey, check if Enterprise
            ProductName = "Product Name: " & objshell.RegRead(Path & "ProductName")
            On Error Resume Next
            sValue = objshell.regread(Path & "ProductID4")
            If Err.Number 0 Then
            Err.Clear
            Enterprise = False
            Else
            Err.Clear
            Enterprise = True
            End If
            On Error goto 0
            If Enterprise = True then
            ProductID = "Product ID: " & objshell.RegRead(Path & "ProductID4")
            Else
            ProductID = "Product ID: " & objshell.RegRead(Path & "ProductID")
            End If

  52. Worked perfect. NIRSOFT PRODUKEY failed on this, but your script got a correct key instead of an “invalid” key.
    Was able to run the Windows 10 Pro Upgrade after replacing a hard drive.
    Thank you !!!

  58. Would this be able to be adapted for finding the product key for Microsoft Office 2016 in Windows 10? I have a lifetime license but lost the product key, and I’m having serious error messages in Microsoft and would like to reinstall. However, Microsoft is telling me I’d have to rebuy the software… if I could just view my product key that would be amazing.

    Thank you so much for your help, this is an invaluable site!

  81. Hallo,
    I have to do inventory for like 30 Pcs. Do to the fact, that we don’t have the key for all the computers, I searched for a method to get them. The first softwares I tried just gave me the generic Code “VK7JG-NPHTM-C97JM-9MPGT-3V66T”. To make sure that I really become the right key, I now try the method on a Pc where I know the key first.
    Now the skript worked and I really got a key, but it’s also a generic key “NF6HC-QH89W-F8WYV-WWXV4-WFG6P”.
    Is there another method to find the original key?
    P.S. sorry if my english isn’t the best
    Yours,
