I always used to check the windows versions by their major/minor build numbers. Strangely enough, Windows 7 and Server 2008 R2, both return the same major/minor version number combination.
Confirm this by typing ver into a command prompt

A:
GetVersionEx. There is a chart of the version numbers and their associated editions here. Notice that the product type is different between 2008 R2 and Windows 7.

A:
This is a good starting point, but you'll need to pay attention to all the fields in the osVerInfo structure, not just the major & minor versions.

It does not mention Windows 7 and up!

No, it doesn't - but it is a good starting point. Refer to the chart from Bruce McGee to get the extra info you need.

It's a little more complicated than you think. I ran across this in a newsgroup somewhere (don't have info on who originally wrote it, unfortunately). It hasn't been updated for Win7 and Server 2008 R2, but the info the others posted should give you what you need to add.

A:
Well, GetVersionEx is nice, but it can be a little more complex than that, especially when users are playing with the compatibility settings.
Read on this excellent post by Gabr...
And look at this previous SO question.
