Since 4.0 a few people have reported issues running on different Windows versions (mainly 8.0, 8.1, and 10). Most of these related to display and compatibility modes. For example see the following conversations, but also note that a quick search didn't pop up newer than a year ago:
My guess is that if it is 'not officially supported' (curious if you saw this stated somewhere 'officially') it's mainly because the primary developers are not working from Windows systems and the people packaging the Windows version haven't been able to fully vet the program on that platform.
