How to Remove a Drive Letter in Windows 10

Windows 10 assigns an available drive letter to a new drive connected to the computer. The operating system goes through the alphabet from A to Z to find the first available letter to assign it to various drives. It is possible to remove a drive letter assigned by the OS.


Historically, Windows reserves the drive letters A and B for floppy drives. Modern Windows versions assign the letter C to the system partition on which Windows is installed. Even in a dual-boot configuration, Windows 10 displays its own system partition as C:.
