Creating a BAT File on Windows
Open notepad by going to Start > All Programmes> Accessories> Notepad.Or, you can just type “notepad”, without quotes, into the start menu and hit enter. Copy the following code: @echo off :W if %time%==00:00:00.00 goto :X goto :W :X shutdown.exe /s /f /t 60 /c “Go to bed!!!!!!” This constantly checks the time to see if it is midnight and, if it is, it shuts down the computer with the message “Go to bed!!!!” Change the if %time%== part to a time of your choice. It must be in this format: HH:MM:SS.MS and in 24 hr format otherwise it won’t work.
Go to File> Save As. Change the “Save as type” box to “All Files” Type “timer.bat” into file name and click “Save” Double click the file. A blank command prompt screen should appear.
