Since I 've had 2 Windows 7 computers for a little over a year, and the other one is XP, I figured I'd better get a book about it JUST IN CASE I ever have a problem, and do NOT have a book IN HAND. The Windows for Dummies books have always been a "lifesaver" when disaster strikes. (( my first computer, not windows, came with about 5 books... my next 4 computers were also Mac )) There wasn't a single problem that I couldn't look up or find reference to inside them. Today's computers come with the owners info ON the computer!! Hey! If the darn thing won't work, how can you read the OWNERS MANUAL ???duhhhh
