While you may never need to change a drive letter, it can be really handy to do so to keep your computer organized and customized just as you'd like.
You can change drive letter assignmements for hard drives, optical drives like CD/DVD/BD drives, and even flash drives. You can not, however, change the drive letter of the partition that Windows is currently installed on.
The specifics steps required to change drive letter assignments from the Disk Management tool differ somewhat depending on your Windows version:

Warning: Changing drive letter assignments for drives that have software installed to them will almost always cause the software to stop working. Most people do not have software installed to drives other than the primary drive (typically the C drive) but if you do, this is your warning that you will likely have to reinstall the software after changing the drive letter.
Important: As I mentioned earlier, you can not change the drive letter of the drive that the Windows operating system is installed on. However, if you'd like Windows on a drive other than C, or whatever it is now, you can make that happen but you'll have to complete a clean install of Windows to that other drive letter.
