How to Change a Drive Letter in Windows Disk Management

Sometimes Windows assigns an inconvenient letter to your new USB flash drive or internal hard drive. You can easily reassign it to any available letter using the built-in Disk Management tool.

Here is a safe, step-by-step guide on how to do it without installing any third-party software.

What You Will Need

• A computer with Windows 10 or 11.

• Administrator privileges.

Step 1 — Open Disk Management

1. Right-click on the Start button (the Windows icon) on your taskbar.

2. Select Disk Management from the menu that appears.

Step 2 — Change the Drive Letter

1. Find the drive you want to change in the list.

2. Right-click on that drive's block and select Change Drive Letter and Paths...

3. In the small popup window, click the Change... button.

4. Open the drop-down menu next to "Assign the following drive letter" and select your preferred letter from the list.

5. Click OK. A warning message will appear stating that some programs might not run correctly. Click Yes to confirm.

Result

The new drive letter is now assigned. You can open File Explorer immediately, and you will see your drive listed under the new letter.
