Restore Missing CD or DVD Drive

Reports have filtered in that CD or DVD drives will suddenly cease to exist in XP and Vista systems. Most often this
has been reported in conjunction with program installations and Windows upgrades, but it has also
happened for no apparent reason. This tweak will restore the missing drives after a reboot.
