One thing I should add. I have installed SP2 on many machines without a problem. SP2 works well on "most" machines. However..there are the "few" that have issues. My point is..don't fix what aint broke. Do a google for SP2 issues/annoyances. Not everyone is happy with SP2. One thing to remember..use the system restore feature! Create a restore point before you try SP2....if your system doesn't like it..roll back to your restore point. Good luck.

It's a shame stupidity isn't painful.
