If you find that you need to refer to your drives by letter more often than nickname, flipping through the Windows Explorer sidebar can be just a little annoying. Here's how to show those letters first in your list of connected drives.
All it takes to do this is a simple registry hack. Hit the Start menu and type regedit into the search box, then right click on regedit.exe and hit "Run as Administrator". You'll need to create a new key, so navigate to:
Right click in the right hand pane and hit New > DWord (32-bit) Value. Name it ShowDriveLettersFirst and hit Enter. Then double click on it and change its value from 0 to 4. Restart your computer (or restart explorer.exe and you should see that all the drive letters will show up at the beginning of the drive's name, as shown above.
To return to the default behaviour, just set the key's value back to 0. You can also set it to 1 to show only network drive letters before the name, or 2 to remove drive letters altogether.
