Hi
First we'll need to backup registry:
Start -> Run -> regedit -> ok. Then File -> Export. Give it a name and press Save.
Save text below as fix.reg on Notepad (save it as all files (*.*)) on Desktop
Windows Registry Editor Version 5.00
[-HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\DriveIcons]
It should look like this ->
Doubleclick fix.reg, press Yes and ok.
(In case you are unsure how to create a reg file, take a look here with screenshots.)
Reboot.
Is it now gone?
