Warning! Do NOT apply XP SP 3!

[AgentZero]

I tried updating to SP3 a few days ago. Didn't get too far. I created a nice little screenshot compilation of the joys of Windows update, I'll throw it up here when I get home.

Then of course there's my classmate who tried to apply SP1 for Vista, and it took three days for it to reach 100% complete, another 4 hours before it told him that the update had failed and it was reverting it's changes, and then another two hours for it to crash and for him to find out that his Vista installation was completely borked and would require a full format & reinstall.
