Out of the blue yesterday started getting "Critical Error your start menu isn't working. We'll try to fix it the next time you sign in"
So of course done the sign out and back in, still no go, done the google search which suggest amongst other things to try a system restore, which I have just completed, with no change.
So what now, really don't want to re-install windows, anyone else had this problem and managed to get it sorted out?
