1. Check the name of the account you’ve logged into (Click start. You
   will see the name of the account you’ve logged in.)
2. Launch the command prompt. (Start | Run | cmd | [Enter] )
   in command prompt, create a schedule to run cmd.exe.
   To create a schedule type the following line and hit enter.
   at 10:41 /interactive “cmd.exe”
   this will create a schedule to run cmd.exe at 10:41.
   (Since you are testing, check the time in your system try and add two or three minutes.)Change this time according to your local time
   Hint: you can check if the schedule is placed by typing “at“
   and hitting enter after the above step.
3. Wait for the time you set for the schedule.
   cmd.exe would be launched at the specified time.
4. After cmd.exe is launched by the scheduled time, press [CTRL] + [ALT] + [DEL] and launch task manager.
   Select “Process” tab, select explorer.exe in the process list and click “End Process” button.
   You will receive a confirmation dialogue. Click “Yes” to end the process.
5. Close task manager by clicking the close (X) button.
   Close the first cmd window (be careful to close the first one not the second one.)
6. Now you have only the second command prompt window and an empty desktop.
   In command prompt type the following line and hit “Enter”
   cd ..
7. In command prompt type the following line and hit “Enter”
   explorer.exe
   If this is the first time you do it, windows creates the necessary
   components for you to access System ( Desktop, start menu,
   My document)
   when it’s finished you will have a new desktop.
8. Close command prompt window. Click start and check your username.
   It’s changed to System.
   Now you are a super-power user. Be careful not to harm your PC and delete or modify system files if you don’t know what you are doing.
