A colleague recently asked me, how he could Change the Drive Letter of a Mounted Device, when he removed a Device. I’m not sure of a reason to do this, however for future reference, i’ll leave a note here…

HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\C:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\D:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\E:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\F:
HKEY_LOCAL_MACHINE\SYSTEM\MountedDevices\DosDevices\G:

Simply rename the Value Name of each Key in the registry using regedit.
