MCE (Media Center Edition) has a major error in it, but if you get lucky you wont get it, but if you unlucky you have a major problem. MCE is part of window vista because vista has it built into itself which makes you more likely to get the error on vista. Then windows xp.

That is where the problem lays, if you update your computer you can update it to where it corrupts CHKDISK, and put it into an Infinate loop because you start to download Vista things now.

Microsoft knows about the error, its intheir Knowledge base, their Fix: None. basically it puts you into an infinite corrupt CHKDISK loop, and can Kill your computer.

Unfortunatly reformatting into MCE again does NOTHING at all.

This may keep you from playing "the world".
