Automated Restarts or Shutdown

Want to shutdown or restart your Windows automatically at a specific time you have defined before? Just follow these simple steps:

Click on Start – Programs – Accessories – System Tools – Scheduled Task to open Task Scheduler. In the Scheduled Task Wizard, use the Browse option and navigate to C:\Windows\Rundll32.exe. Click OK and finish the wizard including select the start time (time to restart your Windows). Once it's done, right click on the newly created task, click Properties, and add the following parameters in the Run line:

C:\Windows\Rundll32.exe shell32.dll,SHExitWindowsEx 0x2

Make sure the "Start In:" box contains C:\Windows. Also the "Enabled" box at the bottom of the dialog has checked. Click OK and you have finished the job.

Note:
If you want an automatic shutdown instead of an automatic restart, use the same procedure to locate C:\Windows\Rundll.exe file. And then add the following parameters in the Run line:

C:\Windows\Rundll.exe user.exe,exitwindows
