Hi
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.

The Linux method you used only gives a small amount of info.

sudo cat /sys/firmware/acpi/tables/MSDM | strings | tail -n 1

but it will match one of the above.

Hi, @adangreen 

The product specs for your model indicate that it came with W8.1 'standard,' not Pro.

https://support.hp.com/us-en/document/c04595131

If you upgraded to W10 then you would install W10 Home.

If you did not upgrade to W10, download the plain W8.1 ISO file from the link below.

Use the Microsoft tool that I zipped up and attached below that you will need to transfer the ISO file to a DVD or USB flash drive so that it is bootable.

After Windows installs, you can install the drivers and available software from your notebook's support page.
