Hi
I thought he said that he tried to Reset, Windows 10 as his first choice, then when he couldn't do that, opted to go back to Windows 7.
You've given him the option to go back to Windows 7 so he should be all set one way or the other.
Personally my opinion is that he should try to clean install Windows 10, before reinstalling Windows 7 and be up to date.
We're going to be stuck with W10 for a long time t come. whether we want to or not . LOL
I tell people to make a system image at least 6 times a week.
If people would just get the message before they have to go through a hassle like this.
