The Version9X property gives the version number for 9x versions of Windows operating systems.
The value of this property is an integer: MajorVersion * 100 + MinorVersion. The property remains undefined if the operating system is not a 9x version. For more information, see Operating System Property Values.
Condition expressions can test for the version by using the property name or may verify the version by using a comparison operator.
