VMware is a company name. I'll assume you meant you are using the free
VMware Server software.
I haven't use VMware Server for a couple years (personally I distaste
their web-centric setup in version 2 but understand why they did it for
remote admin purposes). When I last used it, and when I started a guest
(VM), it prodded me with a prompt asking if I wanted to disable
autoplay. It's suggestion was to disable it but I rejected their
recommendation and left it enabled. Once you accept, however, there was
no undo option to revert to autoplay enabled in the host OS so you had
to do the registry edits.
Since they are just registry edits, I would assume a good tweaker
utility would cover the autoplay settings. Ultimate Windows Tweaker
(for Win 7), for example, and according to the screenshots shown at
http://www.softpedia.com/progScreenshots/Ultimate-Windows-Tweaker-Screenshot-115432.html,
has its "Disable Autoplay function for removable devices" settings (that
you would deselect to leave autoplay enabled). But then you really
don't need a tweaker and can just use the Autoplay applet in Control
Panel; see:
