Question by Jay: Why the heck is Windows 6.1 called “Windows 7″?
I can understand using a name instead of a number: like Windows “Vista” (for Windows “6″), and “XP” (for Windows “5.1″), etc..
But a number in place of a number (“7″ instead of “6.1″)??

And you believe Win7 is really called 6.1 for what reason?

“That brings us to Windows Vista, which is 6.0. So we see Windows 7 as our next logical significant release and 7th in the family of Windows releases.
We learned a lot about using 5.1 for XP and how that helped developers with version checking for API compatibility. We also had the lesson reinforced when we applied the version number in the Windows Vista code as Windows 6.0– that changing basic version numbers can cause application compatibility issues.
So we decided to ship the Windows 7 code as Windows 6.1 – which is what you will see in the actual version of the product in cmd.exe or computer properties.
There’s been some fodder about whether using 6.1 in the code is an indicator of the relevance of Windows 7. It is not.”
