Windows 10 in automatic mode assigns all external and internal devices connected to the PC, a letter from the alphabet from A to Z, which is currently available. It is assumed that characters A and B are reserved for floppy disks, and C for the system disk. But this doesn't mean that the user cannot independently redefine the letters that are used to designate disks and other devices.

There are several ways to change the drive letter in Windows, so let's start with the simplest:

Using the Disk Management utility

  1. You need to hold down "Win + R" and in the "Run" window enter diskmgmt.msc, and then click OK.
  2. Next, you must select the drive for which the letter will be changed, right-click on it and select "Change Drive Letter and Paths ..." from the context menu.
  3. Then click on the "Change" button.
  4. Next, you need to select the required drive letter and click "OK".

Using the "DISKPART" utility

  1. You need to hold down "Win + R" and in the "Run" window enter cmd, and then click OK.
  2. Enter the command "diskpart" and press "Enter". Then a new window will open.
  3. Use the "list volume" command to get information about the logical volumes on the disk and their numbers. For example, let's select drive C, which has number 1.
  4. Select the logical disk using the "select volume [number]" command.
  5. Assign a new letter using the command "assign letter=[letter]"
It is worth noting that changing the letter of the system drive may lead to the fact that some programs that use the previously used drive letter during initialization will stop working. But this problem is solved either by reinstalling the software, or by configuring it.
