Well put Broni. Examples:

1. Losing internet connection. Two long telephone sessions with Dell Tech left to his suggestion that I "Return to the factory condition" (Must be a new Dell corporate motto). A few days later a remark by one of the Moderators dealing with unrelated problem that restart often cures minor Windows irregularities gave me a clue. I stopped putting my desktop to sleep, and shut it off every day. Problem solved.

2. Now to SP 1. After seven attempts at installing SP!, three of them under MS Tech's supervision, and many hours of trying this and that, the magic phrase re-apered: "Return to factory condition". I foolishly succumbed this time, and SP1 got installed, confirmed by the system screen. As all good things come to an end my computer crashed on the next boot the following morning. Had to recover with Acronis rescue disk. Fortunately I made an image just prior to my adventurous return to the factory condition.
