How to change the icon of a hard drive

1 - Go to Search and type "regedit".

2 - On Registry Editor Window, use the left sidebar to navigate to the following key:

"HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons"

3 - Create a new key inside the DriveIcons key. To do this, right-click on the DriveIcons key and select New > Key.

4 - Now name this new key using the drive letter that you wish to change. For example, we are changing drive D here.

5 - Next is to create another key inside this just created drive letter key. To do this, right-click on this drive letter key and select New > Key. Name this new key "DefaultIcon".

6 - Select this newly created "DefaultIcon" key from Left pane and then go to right pane and double-click on Default value to access its properties window.

7 - Now on the "Edit String" window, type the full path of the ICO file(surrounded by quotes) that you wish to use as new drive icon into the "Value Data" box and tap OK.

Example of icon path: "D:\Program_Files_2\Groudon.ico"

8 - In case, you wish to reverse the changes, go back to Registry Editor left pane and select DriveIcons key. Now delete the drive letter key you created.
