well the one i got is off official microsoft website so its not gunna be too dodgy if microsoft are offering it for the public to download ? plus when it installs it installs over version 10 so you dont have to do anything

Had it a few days now and nothing bad to report, the SRS effects and bass enhancer thingy are great, really adds bass when im wearing my stereo headphones Been told version 10 had it though which i didnt know?
