This should be a future proof OS version compare function. I've been burned a few times with old scripts using @OSVersion to do version detection when a new OS (like Windows 7) comes out, since @OSVersion tests are usually done explicitly (If @OSVersion = "WIN_VISTA"...). I've had this laying around for a bit but didn't release it due to a bug in AutoIt < 3.3.1.0. But then it meant it would only work with >= 3.3.1.0, and older versions of AutoIt would get incorrect results, but no err
