oh, I slipstreamed Sp1 like a LONG time ago when did that come out? like over a year ago? Then i just did SP2 ... It would be in your best interest to get the updates...
SP1 slowed down my computer. I'll try it again sometime and with SP2...... slipstreamed which I haven't done. For me, the best thing about XP is the cleartype option which makes text on LCD monitors very sharp. If not for that, any OS from Windows 98 on up is OK with me.
