The particular methods (RegRead, RegWrite, RegDelete) are implemented in version 1.0 of WSH. v 1.0 exists on every windows os starting from win98. So the only users that will not be able to use the aliases are win95 users. It is generally believed that they have become extinct, but for the few remaining ones... well, sucks to be them.
