How to Change Drive Letter in Windows 10

By default, Windows 10 automatically assigns drive letters to connected drives, including internal and external drives. You might want to change these letters. Here is how it can be done.

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. Historically, it reserves the drive letters A and B for floppy drives.

Modern Windows versions assign the C letter to the system partition which Windows is installed on. Even in a dual-boot configuration, Windows 10 displays its own system partition as C:.

Changing drive letters will allow re-arranging drives in the This PC folder. This can be useful after you add an extra drive or create a new partition. For example, you might want to change its drive letter to display it before the DVD drive. Also, when you change the drive letter of a USB drive, it will be assigned permanently. Often Windows 10 randomly changes the drive letter for external drives when you connect them, so this way you can make this process more predictable.

Tip: Show drive letters before drive names in This PC / Computer folder.
