You know what they say, if it is to good to be true you know it is, leave it alone.
Why MS is doing this? I agree with you maszsa. too many times or should I say mostly all of the time MS roll out their stuff and they know it is not ready! We test it and give them feedback that they already know what is wrong with their stuff.

If it is okay I will try it if I can downgrade to windows 7 pro otherwise I will stay with windows 7 home prem. which I am not happy with. No group policies as in Win XP pro.
