The VersionNT property will get the major.

You'd have to go more in depth if you were searching for Home / Pro / etc editions.

For InstallScript, there's also SYSINFO.

There are keywords WINMAJOR and WINMINOR whcih can be used to check the OS major version and minor version repectively.

For Vista,
Major version = 6
Minor version = 0

For Windows 7 ,
Major version = 6
Minor version = 1
