Ok, Windows 7 was ok, Windows 8 sucked, they left out version 9 - so Windows 10 should be good again
Apparently, the name Windows 9 would have caused problems with buggy software identifying the OS as Windows 9x - like Window 95 or Windows 98.
Also, 9 is a bad luck number in Asian countries just as 13 is in Western countries. Don't want your overseas market spoiled because of a badly chosen version number
