OS Versions

[Andy]

I am looking for a list of the latest os major & minor versions & build
numbers so that I can differentiate Client and Server OSes. Where can i find
such a list?

Also, how do I tell if an OS is 64 bit? Are the major/minor versions or
build numbers different?

All the lists of info I have found so far are well out of date and do not
touch 64-bit OSes

build numbers different?

The last time I saw this question asked I do not recall seeing a
satisfactory response. I'd be interested to hear a definitive answer.

If you're using Vista or above, I believe you can query the
Win32_OperatingSystem.OSArchitecture property using WMI.

The answer hasn't changed. What's unsatisfactory?

If sizeof(IntPtr) is 8, you're a 64-bit application on 64-bit Windows
If IsWow64Process succeeds and returns true, you're a 32-bit application on
64-bit Windows
Otherwise you're on 32-bit Windows
