Only partially correct. Engineering saw it as an incremental update to Vista. Marketing wanted something that said, "It's not Vista".


>The 6.1 thing is only for compatibility issue. Some software only check the first digit when verifying the OS version. So if they use something like

IF VERSION() = 5 OR VERSION() = 6
>   *-- Proceed
>ELSE
>   *-- Wrong OS
>ENDIF

the software will still run under Windows 7. If they changed the version to 7.0, the code above would have broken.
