Useful modules (standard with ActivePerl)

Win32::Shortcut
Win32::TieRegistry

NB: Win32::Shortcut doesn't appear to have any POD documentation. I know there is some info in Dave Roth's book on Win32 Perl Programming. For the other, try perldoc Win32::TieRegistry from the command line. (or look at the html docs that come with ActivePerl).

By the way: do you just want to find the System path? You could probably use $ENV{SYSTEMROOT}

Hope this helps!
