I think that Rich's generic advice is very sound: Messing about with all
this stuff is bound to lead to trouble.

Bearing that in mind, I am eminently suited to offer suggestions because I
know nothing about Vista.

Conceivably the message "access denied" is just some stupid
program's error message when 'net stop' failed. That is, it's not really a
permission problem, but something to do with the fact that the service or
something it controls is active, so it can't be stopped at the moment.

The correct procedure would be to set the Startup type to Disabled, then restart.

On XP I would use services.msc or set registry:

HKLM\SYSTEM\CurrentControlSet\Services\
Start = 4 (Disabled) - Don't start the driver on boot
