Then create a file called: autorun.inf in c:autorun.inf
then open that file and type the following:
save and close the file.
Now open my computer and refresh.. and woh! icon changed….
you can apply to other drives too.
“autorun.inf” and “ico.ico” must be in the root of the drive.

same on the root.
