This is a personal PC one - normally I wouldn't have an issue, and I've already logged a call with MS but in the meantime, will ask if anyone else has had this.

Normal home PC. No hardware changes. Yet in the last 2 weeks, it's told me 4 times that it has detected hardware changes and requires manual reactivation.

Annoyed isn't quite the word for it. Any ideas before I do the unmentionable?
