Linux: Read embedded Windows key from BIOS

Post by ^rooker »

I have bought several notebooks that had Windows preinstalled, but the license key was only stored in the BIOS (no more stickers on the bottom like in the good old days).

I never used the Windows on the more recent machines, and only have GNU/Linux installed on it. However, I like to know license keys I've paid for, so here's how to read it from Linux:

Code: Select all

$ sudo tail -c +56 /sys/firmware/acpi/tables/MSDM

Thanks thread #637971 on superuser.com for this tip.
