When the setting refuses to take at all, something already running is holding your file associations, and one owner traced exactly what.
It makes a new PC feel like your old one. It does not get your old PC back, and the free allowance it uses is only five gigabytes.
The fix one owner confirmed was not a product key at all. It was a repair install, after re-entering the key returned a second error.
Four situations, and only one of them is a decision. An unapproved processor cannot be fixed by any setting, and most pages skate past that.
