Thanks both for your thoughts, I am recieving but not seeing the notices, Media centre stays on top. The event viewer has the warnings, currently I can get automatic updates. At login I get a notice about activation being required, but I just cancel it out & I'm allowed to continue. I seem to remember with XP you reached the point where you had to activate, no activation, no login. I'm not sure if I want to take the risk of leaving it unactivated as I'm using media centre more & more. So far no reboots or darkened screens! regards
