If your CD-ROM Changer cycles excessively, try these 3 simple steps:
1. Set HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\Autorun to zero.
2. Set the "Start Up" of CD Audio in Control Panel / Devices to Manual. Press the Stop button (This may not be required on your installation).
3. Create a shortcut to Explorer (set to minimized) and place it in your Startup folder. Leave it minimized. It will share the CD information with all other copies of Explorer that you open and with all properly written applications.
