And this is a big part of why, before I let any XP install anywhere near the net, I kill Windows Update. I'm happilly running SP1. "But... But... You're crazy... What about those bug fixes in SP2... You NEED SP2!"
The way I see it is this: If you bought a car, and the doors and wheels fell off when you left the dealership, would you trust that dealer when they said "Okay, honestly, it's all fixed now. Trust us!"
And as someone said, use Ubuntu. Story a week or two back of someone who did that managed to get validated as genuine Windows.
So far the only time this WGA crap has screwed me (and my XP is technically legit. I had to do a reinstall, but didn't want to use the recovery disk as the Norton install on said disk is botched leaving IE unable to open stuff from Microsoft's own website, so I used an old XP disk I had kicking around) was when I needed the .NET framework. But it took me 2 minutes to find it on another non-MS site.
Fuck Media Player... Videolan/VLC for video, Foobar or Musikcube for MP3's. Foobar includes a ripper, you just need LAME on your system.
Why anyone uses Media Player is beyond me.
