Hi,

How can I determine which version of Windows XP 64 Bit I'm having? I haven't got the final yet so I would like to give the latest RC a try. I just want to make sure I've got the latest though.

If I look at the version info of the setup.exe file I get to see version 5.1.2600.0.
Is this the actual build?

Which build version does RC2 have? Or is there even a later edition? If yes, which build version does that one have?
What build version does the final release have?

Is there no way to accurately determine the build of the installation?

if you look on the cd for any of the dll files, they have the version info
my RTM has version 5.2.3790.1830 dll's created on the 25/03/2005

hope this helps

Well I guess that does'nt really work unless they have'nt changed anything between the final and the RC2 version as all of my files on the CD state MODIFIED 25/03/2005 and I have Windows XP 64bit PRO RC2.

Your version (above) is the same as my version 3790 hence: 5.2."3790".1830, but the best way to find out, is install the software and they boot into safe mode, it says the version number all over the edges of the screen.
