Fix Windows Activation failed due to Software Protection Service error code 0xc0000022
With Windows Activation, the fun never ends!
Recently I reset a laptop with OEM Windows 10 Home for a friend. All I did was use the built-in Win 10 “factory reset” that should have wiped everything, reinstalled Win 10, and then reactivated just fine.
Alas, that’s not what happened…
Instead, I got error code 0xc0000022, and the perfectly valid built-in OEM key would not re-activate the same Windows on the same hardware – no matter what I did.
It turns out the culprit was an ‘access denied‘ error in the Software Protection service…
