Windows 10 product key/licence

[Bowline5]

Where can I find the licence key for my W10 operating system? The OS came pre-installed when I bought the notebook so the Microsoft referred me to the manufacturer, who then bounced me off to the retailer. Their support service doesn't even know what a licence key is! There must be a record in the archive somewhere, but how do I get to it?

Hi

Doing research, and none of the methods are mine, I have 3 lines of code that will list the same value for your Windows 10 Product Key…
Two for Windows 10 and one for Linux.

W10 Using cmd.exe as an Administrator (copy and paste accordingly).

wmic path softwarelicensingservice get OA3xOriginalProductKey >> c:\ProdKey.txt

Creates a text file called ProdKey.txt on your C:\ area.

Next is a PowerShell command, as Administrator...
(Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

but it will run within W10 using cmd.exe as an Administrator.
powershell (Get-WmiObject -query ‘select * from SoftwareLicensingService’).OA3xOriginalProductKey

Last, but not least....
Linux@Lubuntu:~$ sudo cat /sys/firmware/acpi/tables/MSDM | strings | tail -n 1

Thank you for the help. Typically Windows 10 did not perform as Microsoft says it should, I was denied access to set up the Product Key text file, but the Powershell command instantly returned 5 groups of 5 letters and numbers. Job done, thanks again.

Hence the Multiple Choice.
