No, not necessarily. See this past September's issue of the VFUG (www.vfug.com) newsletter for the article "Introduction to the Windows Script Host" that Ed Rauh and I wrote. Among other things, it tells what versions of Windows it comes with, and how to check if it's installed. The Scripting.FileSystemObject will be covered in next month's (November) issue.
