How do I change the registry (default) string. I am trying to turn off autorun using this reg entry:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\IniFileMapping\Autorun.inf]

FYI: If you used an import.reg script it would look like this @="@SYS:DoesNotExist"

That doesn't work and if I use the (default) import I get an extra (default) registry string entry which does not work. Any thoughts?
