Had a strange thing happen to my Dell E521 Desktop this morning. Turned it on and typed my pw as usual and didn't wait for the desktop to show or anything so I don't know what transpired. I then went to make coffee. Came back about half an hour later to check my mail and the generic Vista desktop was up with a handful of icons and a Dell user agreement wanting me to agree or disagree with the terms as if I was turning the computer on new out of the box. I did a restart and logged in again and everything came up as usual. Just wondering if anyone else ever had this happen and what it might portend?
