Renaming CD ROM Drive Letter

Rename the drive letters of your CD drive(s) from the back of the alphabet, eg, Z, Y. This way, if you add extra hard disks, your CD drives do not get re-lettered.
1. You can do this from the Device Manager.
2. Open up the CD ROM section
3. Open the CD ROM you want to change
4. Under Settings, change the Start Drive Letter to higher in the alphabet
