"Is it true that microsoft can delete content they dont like? like downloaded music?" Yes this is true. MS, in there blind need to control your computer, put a big back door. It is there so MS can see if you have a non-copied verion of Vista. It also lets MS see what files you have on your PC, and delete ones that they do not like, without you knowing about it. For me this is the main reason I will not be getting Vista, or anything from MS.
