If you work on your computer till late night then you might often forget to shut down your PC. At the morning you would discover that all the night your computer was on. But you can configure your PC to shut down automatically at a scheduled time when your computer becomes idle. Here is the simple workarounds to configure the scheduled task in Windows 7 and XP.
To attain this, you’ll have to configure a Task schedule job that commands the computer to shut down in your Windows system. Also don’t forget to setup the rules so that it should not be fired if you are up and start late to use your PC again.
