Windows 10 20H2: A very minor update

Windows 10 20H2Yet another new ‘version’ of Windows 10!

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…
