To create a shutdown timer manually, open Command Prompt and type the command shutdown -s -t XXXX. The “XXXX” should be the time in seconds you want to elapse before the computer shuts down. For instance, if you want the computer to shut down in 15 hours, the command should look like shutdown -s -t 54000.
If you want to restart your computer on a delay, use shutdown -r -t XXXX instead.
To cancel the timer, open the Run window or Command Prompt again and enter shutdown -a.
Create a shutdown timer shortcut
If you need to use a shutdown timer regularly, you can take this trick one step further by turning it into a desktop shortcut.
- Right-click on the desktop, hover over New and select Shortcut in the side menu.
- In the path field type “shutdown -s -t XXXX” and click Next.
- Enter a name for the shortcut (for example, “Shutdown 1 Hour”) and click Finish.
Any time you double-click the shutdown shortcut, the timer will start. To cancel the timer, you can create a second shortcut using shutdown -a or enter the shutdown -a command in Command Prompt.
To change the time on the shutdown timer, right-click the shortcut icon, select Properties and change the seconds value in the Target field. From within Properties, you can also assign a different image as the icon.
