Open registry editor and navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
Now create a new key named DriveIcons n then create once more under the DriveIcons and named it as the drive letter, that icon to be changed. lets say C
Now create a key under C and named it DefaultIcon and goto right side pane of key. here type the path of icon file in (Default) value such as "C:\Windows\C.ico" without quote.
Open My Computer and press F5 to refresh or commit changes.
Download : About Windows bmps and system drive icon.
