Change The Icons Of Removable Drives

Create your icon, or find one online.

A good size is 34 pixels square.

Open Notepad to create your Autorun file.

Type [AutoRun] in the first line.

Name your drive in the second line: label=Name

Specify your icon in the third line: ICON=your-icon-file.ico.

If you wanted to call your drive "My USB Drive" with an icon named "3GFun.ico", your code would look like this:
[AutoRun]
label=My USB Drive
ICON=3GFun.ico

Click File, then Save As. 

Change the file type to "All" and name it AUTORUN.inf
Ensure that both your AUTORUN.inf and .ico files are in the ROOT of
your removable drive, instead of a folder.
