There are, in fact, very view OS problems being posted. I would say that many are concerned with only two issues, which are quite daunting for new users. 1. The desktop (modern) on arrival at a new installation, and 2. Having finally found the alternative desktop, the lack of a start menu. Number two seems to flood the forums.
Other than that, the very small remainder of OS requests for help are concerned with finding ways to do things - many of which are not really very different from Windows 7, or third party hardware problems, of which there are very few.
There is an minor input from potential users who, in many cases, can easily be detected as using a downloaded OS from an illegal source, ie. Pirated. With improper activation, many problems not experienced by the normal user, can pop up.
