My Advice :
STAY AWAY FROM IT
(and yes, my XP is a legal copy). Just installed SP2 - Killed my PC! OS wont load, hangs on the GUI 1st screen. Tryed a System restore - Failed. Gave up - formatted HDD - reinstalled windows XP
OK, so now i thought fresh install, lets get SP2.
Installed OK, Rebooted , tried to get online - Nothing!
IP adress 169.xxx.xxx.xxx. Unable to get an IP adress from modem OR router.
Thankfully a System restore worked so now i can begin copying my 22gb of .ogg files :-)
- edit
And no, im not going to install SP2
