Was 7 really called 7 because it was the 7th version of the NT kernel? If so, then 7, 8, 8.1(9), 10 makes sense sorta kinda.

  2000 (5), XP (5.1), Vista (6), 7 (6.1), 8 (6.2), 8.1 (6.3)

    And Windows 10 will be 6.4. It just doesn't make any sense.

      One popular theory is that there is software out there that checks for Windows version == 6 instead of >= 6 when deciding to enable features for Vista and above. This was definitely true of libcurl at one point, for example.

        In that case, my vote is for Windows X to be version 6.3.1.

  Windows 7 was NT 6.1. Windows 8 was NT 6.2. They were called that because marketing.
