Sounded like a good idea, so I logged out of the store, but when I went to log out of the Xbox app, it wouldn’t allow it. I tried to run it, but it wouldn’t run either, just the Xbox logo, pulsating in a black screen. Xbox is an embedded app in Windows and won’t uninstall, Repair or Reset. Totally screwed here.
I guess I can do a Windows reinstall, but I’ve never done that and there are varied procedures online as to how to do that. There’s a method in Windows Security called Start Fresh, theoretically doesn’t affect installed apps but, as I said, I don’t know enough about a reinstall to be dangerous.
When Windows10 came out, I was on Win7 and the upgrade was free, so I don’t have any media to reinstall from, nor am I certain how to relate my existing Win10 to a legitimate copy.
