Display drive letters before the names in Explorer(Windows XP, Vista, 7)

             Explorer displays the names of drives first followed by the alphabets assigned to them in brackets. Since you identify drive letters better, you want to place them before the names.
            Just like the previous versions, even Windows 7 does not provide any direct option for the display of the drive letters. You thus need to do this via the registry. For this, start ‘regedit’ via the search field of the Start menu.
            Navigate to the ‘HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Currentversion\Explorer’ key and create a new entry ‘ShowDriveLettersFirst’ there via ‘Edit | New | DWORD Value’. Now open this entry for editing by double clicking it, set the ‘Value’ to ‘4’ and confirm with ‘OK’. The default value ‘0’ shows the drive letter after the name and ‘2’ does not show it at all. Now close the registry and restart Explorer.
