No, this is using the Shell object, which is not a part of WSH, but is an automation object completely independent of WSH (the real requirement is the presense of an Active Desktop compliant shell on the system) and requires that older non-compliant OS releases to install IE4 or apply service patches to get the missing pieces.

The Open method of the Shell.Application object is doing the equivalent of launching the document with ShellExecute(), although it can do more since it will create an InternetExplorer.Application object instance if you launch a folder with it. For this use, either the _ShellExecute() class from the VFP6 FFC or using the ShellExecute() API call (there are about 8.7 billion examples of this on UT in the past, and at least one in the FAQ) will work just fine.
