Check that link and look under the main heading of my processor name where it shows my OS.

yep, just type "winver" in start menu search tool, then enter.

That doesn't specifically say it's Vista, just says it's 6.1 Build 7000

Here's part of the reason why.

Why 7? - Windows Vista Team Blog - The Windows Blog

The Windows Blog said:

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.

So windows 7 really is just a modified Vista and not built up from scratch?

Yes. And so was XP.

XP was just a modified Win2000?
