Thank you!

I had a look on the proposed code and I think there is a major problem with trying to increase only the *minor* version =-O

Let's assume we are on a future Windows 9 and that one has the actual version number 7.0.

GetVersionEx() would still report v6.2, so the first version we would try to check via VerifyVersionInfo() /with the proposed/ code would be v6.3.

But the check for v6.3 would fail! That's because the minor version "3" is *not *GREATER_EQUAL to "0".

So we would stop there and end up with v6.2. Bummer!

With the code that I proposed earlier (and when starting with v6.2), we would /first/ check v7.0. If that worked, then we would check v8.0 next.

And if that didn't work, we would go on to check v7.1. So with my code we should end up with v7.0, as expected...
