Hi,
I just got a new job, and I decided to upgrade from Windows 10 Pro to Windows 11 Pro. It already had a Windows 10 Pro license key preinstalled. I decided to use the Massgrave.dev tool and accidentally changed my HWID to a Windows 11 Home key. Now, I’ve decided to downgrade back to Windows 10, but even when I use the Multi ISO for Windows 10, I can’t select Windows 10 Pro; it just defaults to Windows 10 Home now. I really want to restore my keys. Does anyone know a method?
Licensing and activation are separate, and only loosely related. If you are at anything resembling a large org, they don’t even use the HWID or OEM key- they will be using an internal KMS server.
It really sounds like you have way more permissions than you should have on a work device. You should’ve hit a wall even attempting to install Win11 (I can confirm that my work blocks this very effectively). I also question why you would want to do that at all. I’m also not sure you needed to do anything to activate- I believe 10 and 11 use the exact same HWID/keys/etc
