Windows 7 - How to Modify Drive Letters


Windows 7 automatically assigns drive letters to every drive connected to your computer. On most computers, the "C" drive is the primary hard drive and all other connected drives are assigned drive letters after that. Only the letters "D" to "Z" can be freely assigned to different drives. The "A" and "B" drives are rarely used these days, since they are reserved, by default, for floppy drives. Windows 7 makes it easy to change drive letters for most of the drives connected to your computer. You cannot modify or remove the drive letter for the primary drive on your computer which your operating system is installed on, however. Before you change a drive letter, it's also important to remember that any shortcut assigned to a program installed on the drive will no longer work, since it won't recognise the new drive letter. In such cases, you'll need to create a new shortcut or modify the existing one.

To complete the following task, you'll need to be logged in as an administrator or have the administrator password. Following is the easiest of modifying drive letters, although it is also possible to make these changes by manually editing the system registry.

Open your start menu and right-click on "Computer" in the right-hand side and click "Manage." If you have User Account Control turned on, you will receive a warning. Click "Yes" to bypass the warning and enter your administrator password if prompted to. The Computer Management control panel will appear.

In the left-hand pane, you'll see a list of options allowing you to configure your computer. Open up the section called "Storage" and click on "Disk Management."

Right-click on the drive or partition which you want to modify and click on "Change drive letter and paths."

Click "Change" and, in the next window, choose the option "Assign the following drive letter" and choose your preferred drive letter from the drop-down box to the right. Click "OK" when you're done. An AutoPlay window may appear. Just close it if it does.

You can also remove a drive letter by clicking "Remove." This is a good way of hiding a drive since, if you have a drive without any letter assigned to it, it will not appear in Windows Explorer and most programs will not be able to access it either. You can always assign a drive later on by clicking the "Add" option instead.
