I recently installed Microsoft VM after finding an installer on the Internet
(

_8073687b82d41db93f4c2a04af2b34d.exe). However, I've decided not to use it
anymore and may switch back to Sun's Java (which is presently not installed).
Any idea on how to uninstall Microsoft VM? It's not listed my Add/Remove
Programs window, and I'm not sure the specific files it installed.
