Was curious if you manually tweak the registry to stop autoruns from running on bootup, how will that affect the loading of a rescue disk? Say if I did this: AutoRun can be bypassed by holding down the shift key as the optical disc is inserted into the optical disc drive. It can also be permanently disabled (by a System Administrator) by setting the "AutoRun" subkey in the registry key HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\CDRom to 0. However, even when Autorun is disabled, executing default Explorer context menu command, usually done by double-clicking or pressing Enter, to a drive containing AUTORUN.INF in its root directory will still activate AutoRun, if Explorer determines the drive type is capable of AutoRun. Am I locked out on reboot from using a cdrom then? I have another setting in the bios where I can enable or disable the cdrom. Would I have to do both the registry and the bios tweak to perm disable this and if I did that would I not be able to rescue myself with a cd rom?
