>I am using the command OS(1) to return which version of windows is currently running on a system. It returns "Windows 5.01" (this i guess means WinXP cause thats what I am using). I need to determine what the different values that get returned mean for example is windows 4.01 = WINDOWS ME ? is windows 2.01 = Windows 98 ? Help!?!?
>Also on a simular subject how do you know which Windows Service pack is installed?
