Click "Start", go to "All Programs", go to "Accessories", and right-click "Windows Explorer", click "Properties", and in the "Target" box type or "Copy and Paste" the bold writing:-
1.) "My Computer" highlighted in left side with all drives visible but not expanded and C: highlighted in right side= %SystemRoot%\explorer.exe /e,/select,c:
2.) Desktop highlighted and nothing expanded = %SystemRoot%\explorer.exe /e,/n,/select,/root,c:
3.) All drives visible and the system drive highlighted and expanded in full screen = %SystemRoot%\explorer.exe /e,/select
4.) All drives visible and the system drive expanded in small screen = %SystemRoot%\explorer.exe /e,/select,%systemroot%
5.) Only Windows Directory visible highlighted and expanded = %SystemRoot%\explorer.exe /e,/root,%systemroot%
6.) All drives visible but only C: highlighted and expanded = %SystemRoot%\explorer.exe /e,c:
