Fix for CD Autorun

I recently had a situation where my CD/DVD drive quit autorunning.  If I put a CD in the drive that had an installation program on it, the autorun.inf was never run by the system (Windows XP Pro).  This had been working fine until recently; I suspect uninstalling some of Roxio's crappy software was the culprit.  Anyway, I searched the internet for solutions, checking the registry, making sure the drivers were correct, all to no avail.  Microsoft had several Knowledgebase articles on remedies for the problem - none worked.  Then I thought, it's a plug and play device and doesn't require special drivers to be installed so I just uninstalled the drive in Device Manager and rebooted.  Viola!  XP found the drive, installed the device driver automatically, and autorun was functioning again.  Took all of about a minute (if you don't count my research time).  If this ever happens again, I know what I will be trying first.
