Method 1: Use the Run command to schedule a one-time shutdown

1. Open Run
   Press Windows + R
2. Type the shutdown command
   Type the following and press Enter:

   shutdown -s -t 3600
   

   ➤ -s means shutdown.
   ➤ -t means “time” in seconds.
   ➤ In this example, 3600 = 1 hour (60 minutes × 60 seconds).

   🕒 You can change 3600 to any number of seconds you want.

3. A pop-up will confirm the scheduled shutdown
4. Cancel it if needed
   If you change your mind, open Run again and type:

   shutdown -a
   

Method 2: Use Task Scheduler for recurring shutdowns or restarts

This is useful if you want the PC to shut down daily or weekly at a specific time.

1. Open Task Scheduler
   Search for it in the Start menu.
2. Create a basic task
   On the right, click Create Basic Task, name it something like Daily Shutdown, and click Next.
3. Choose a trigger
   For example: Daily at 11:00 PM.
4. Choose “Start a program” as the action
5. In the “Program/script” box, type:

   shutdown
   

6. In “Add arguments”, type:

   -s -f
   

   ➤ -f forces running apps to close.

7. Finish the wizard
   Your PC will now shut down automatically at the scheduled time!
