[wpkg-users] Package pre-requisites

[Adam Peart]

Or with Windows Xp/2000, you can retrieve right from the registry what 
version & what service pack is installed.
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

ie on a Win XP SP2 machine
CSDVersion = Service Pack 2
CurrentVersion = 5.1
ProductName = Microsoft Windows XP

or a Win2k SP4 machine
CSDVersion = Service Pack 4
CurrentVersion = 5.0
ProductName = Microsoft Windows 2000
