Re: The Windows way
"but really Win7 should have been 6.<something> as an increment to Vista, Win8 was really win 7"
They were, internally. WMI queries to ID the OS version, E.g. for SCCM collections, will show that Windows 7 is NT Workstation 6.1, Windows 8 is 6.2 and Windows 8.1 is 6.3.
The Vista name had to be retired though, because it had such a huge stigma around it.
