A number of readers have reported that setting AutoRun to 0 in Windows XP, prevents Explorer.exe from refreshing it's display of CD-ROM content when you press View / Refresh.
I have been unable to re-created this behavior, so other unidentified factors must be involved.
If you experience this behavior:
1. Set AutoRun to 1.
3. Shutdown and restart Windows XP.
When you change CD-ROM media, press View / Refresh to update the Explorer.exe display.
