Windows Script Host 5.6
Windows Script Documentation
you should make sure that the computers you'll be using have the newest version of the scripting host. that's 5.6, which i've linked to. the second link, is a huge ( and really useful ) help file for writing Windows Scripts. it's full of examples, many of which can simply be copied and pasted.
also, you might want to check out
http://www.winguides.com/registry/ , which has a bunch of information about the windows registry. most of it is for performance tweaking, but it might have the information you need.
