Activate Windows Watermark after activating before?

Press Windows key + X

Click Command Prompt (admin)

Enter the following command:

Thanks for the quick reply, unfortunately, though, I got another error after attempting this with the Command Prompt.

I got

Node - DESKTOP-BMCGM63

ERROR:

Description = The service did not respond to the start or control request in a timely fashion.

I'll try the phone activation, I suppose.

One thing to note though, is that I DO know the key I used when I activated it the first time, as It's on my tower, but It simply won't work to remove the watermark.

Which edition of Windows 10 is installed?

Which version of Windows is listed on the sticker?

Copy the VBS script below into NOTEPAD and then save as ProductKey.vbs...Then double-click the ProductKey.vbs and it will report to you your Product Key....This works for me...

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
