Whenever you connect any drive to Windows 10, either internal or external, the operating system automatically assigns a letter. The same goes when you map a drive and create a new partition. By default, when assigning a letter for a disk or partition, Windows goes from the top of the alphabet to the bottom, omitting letters A and B — those are for floppy drives (yes, still a thing.) C is always a system drive – you cannot change it, and you should not even try. The next drive you connect to your computer gets the letter D, E, F, and so on.
If you want to change a drive letter in Windows 10, you have a few options to choose from. There is no need to download third-party apps just to change a drive letter in Windows 10. Built-in tools are more than enough for any users.
