Rename or assign a Drive letter using Command Prompt, Disk Management, PowerShell, Registry Editor or Drive Letter Changer software in Windows 11/10.

It is easy to do for other drives using the disk manager, but the main drive is another story. But, I figured out a method on how to do it in case anyone wants to.

You may want to change the drive letters Windows 8 assigns to the external hard drives you use for your business if you need to manage drive letters or do not like the letters assigned.

In case you are not able to download Windows Update because of low space on the C drive, you can change where Windows 11/10 download updates.
