Licence Key hopefully by this method....

ShowKeyPlus from the Microsoft Store (probably the best choice).
https://www.microsoft.com/en-us/p/showkeyplus/9pkvzcprx9nv?activetab=pivot:overviewtab

The output is like this....
ShowKeyPlus - Windows Product Key Information

Product Name: Windows 10 Home
Version: 12345.678 (64-bit OS)
Product ID: 00000-00000-00000-AAOEM
Installed Key: 12345-67890-09876-54321
OEM Key: MICRO-SOFTY-WINDO-WSTEN-64BIT
OEM Edition: Win 10 RTM Core OEM:DM


ALSO
KeyFinderInstaller may help.…
It gives this…. – CD Key: 12345-67890-09876-54321

ELSE
There is a possibility of finding the same value in the Registry....
USING RegEdit the key is listed below and it’s content also shown.
Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\SoftwareProtectionPlatform

BackupProductKeyDefault 12345-67890-09876-54321

Three different names for the same value in 3 different software methods.

If in doubt please ask.

Hi

I believe so.

There are default/install keys available, but do not use them unless there is no option as they will fail verification.

Windows 8.1 standard edition:  IT WILL NOT VERIFY AS A GENUINE KEY  --  334NH-RXG76-64THK-C7CKG-D3VPT

Generic Install key only.
