Finding your Windows 10 key can be problematic with Windows 10. Here is a VBS script that can get your key with no issues. This script was not written by me, but has been posted in several places with no recognition of the author. If an original source is found, I will update with the author of the script.
1. Open Notepad.
2. Copy and paste the code below into Notepad.
Set WshShell = CreateObject(“WScript.Shell”)
MsgBox ConvertToKey(WshShell.RegRead(“HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId”))
Const KeyOffset = 52
i = 28
Chars = “BCDFGHJKMPQRTVWXY2346789”
Cur = 0
x = 14
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
Loop While i >= 0
ConvertToKey = KeyOutput
3. Save as windowskey.vbs (Change the file type to “All Files”)
4. Run the file and your key will be displayed.
