Egh... I'm loath to say anything bad about XP, 'cos it's such a huge improvement over 2000 it isn't even funny. After years of having my computer lock up every other hour at best and losing everything to viruses because of some idiot, I'm inclined to be overly charitable towards any OS that doesn't lock up just sitting there and can run all my programs relatively well. And is idiot-proof, in that the computer I run it on has me as admin, and I locked all the idiots out.
I don't know what you're doing to your computer, an0n, between this and the installer mess-up... But yeah, it seems like Microsoft's stopped accounting for when things actually do go wrong.
