Hi Stan:

Windows 98 Second Edition.
System Properties: Microsoft Windows 98 Second Edition, 4.10.2222A
OS() returns "Windows 4.10"

Windows 95
System Properties: Microsoft Windows 95, 4.00.950
OS() returns "Windows 4.00"

>I am running Windows 2000 and OS() returns "Windows 5.00"; the Hacker's Guide says Windows NT 4.0 will return "Windows NT 4.00" and Windows 95 will return "Windows 4.00" which doesn't make sense to me. Could that be a misprint?
