File Types change button grayed out for Limited User

Archived from groups: microsoft.public.windowsxp.customize (More info?)

I don't know why I can't use Windows Explorer
tools/folder options/file types/change (because it's
grayed out when logged on as a Limited user), but have
found an alternate way of setting the association.
