Yes, from what I read on their 360 forum (translated , of course) , there won't be any XP versions anymore and no 32-bit, also. From what I understood they're forcing everyone to the chinese win10 "government edition". Also, tried this pile of garbage on a spare win7 machine , not launching . Says something about "your PC is insecure , reinstall 360 browser and try again" . Guessing it's because I don't have telemetry updates , in fact , I don't have any updates on that machine at all . It's a testing dump .
But hey , don't forget 64-bit Vista users !)))
