SP3 made an absolute disaster of the one machine at home I put it on. I will not add it to another, nor my work laptop.
I got my first blue screen ever after putting on SP3, that is in over a year. How did I blue screen? Opened Mozilla, loaded a page with a java applet. That was it.
It now takes almost 5 minutes to boot. I get the splash screen and the machine hangs. SP3 cannot deal with the fact that I have one hard drive plugged into my secondary controller that is disabled. It now finds only 1 of 3 scsi CD ROM drives.
Oh, and I got rid of that automatic update junk. Even though I said no it was still loading. Go into services, stop it, then disable it.
I hope SP3a comes out soon.
