A PC shutdown timer you can see counting
Search for a PC shutdown timer and nearly every result teaches the same trick: press Windows + R and type shutdown /s /t 3600. It works, but the number is in seconds, nothing on screen shows how long is left, and the only way to cancel is to remember shutdown /a before the deadline. If you wanted sleep or a lock instead of a full power-off, the command does not help at all.
PC Shutdown Timer puts the whole job on one round dial. Drag around the ring to pick the minutes, or enter figures into the Hours, Minutes and Seconds boxes below it. The time in the center of the dial is also the button: click it to start, and click it again to stop. As the countdown runs, the ring drains so you can read the time left from across the room.
Above the dial, a plain sentence says what is going to happen and when, such as Shut Down Computer in 2 hours. You read it before you commit, not after the screen goes black.
How to set a shutdown timer in Windows 11
The steps are the same on Windows 10.
- Open the Behavior list and pick what should happen at zero: Lock Computer, Log Off, Force Log Off, Restart Computer, Sleep Computer, Hibernate Computer or Shut Down Computer.
- Under Timer Type, choose Countdown Timer to count down from now, or Specific Time to fire at a date and time on the calendar field.
- For a countdown, turn the ring or fill in Hours, Minutes and Seconds.
- Click the time in the middle of the dial. Close the window if you like; the countdown keeps going as an icon by the clock.
- To cancel, click the middle of the dial again, or right-click the tray icon and choose Stop the timer.
Schedule a shutdown for a clock time, not just a delay
A delay is fine when you know how long a job takes. Often you only know when you want the machine off: after a download that should be done by 2 a.m., or before the office closes. Specific Time handles that case without any arithmetic. Pick the date and time and the app works out the countdown for you.
If the moment you choose has already gone by, the headline says Set a time further ahead instead of firing straight away, so a typo in the hour cannot switch the PC off on the spot.
A sleep timer for your PC, with a warning first
Not every night ends in a full shutdown. Choose Sleep Computer or Hibernate Computer and the same dial becomes a sleep timer for your PC, handy for music or a film you fall asleep to. Lock Computer suits stepping away from a shared desk on a timer.
With Warn one minute before turned on in Settings, a Windows notification appears when sixty seconds remain, giving you time to save or stop the countdown. A separate option, Prevent PC From Sleeping While Running, holds off sleep and the screensaver until the timer fires, so a long render or upload is not cut short by your power plan before the planned shutdown arrives.
Powering off or rebooting requires a Windows right that not every account holds. The app asks for it the moment you press start, so if your account is not allowed, you see the message right then instead of finding the PC still on in the morning.
