How to Automatically Shut Down a Windows 10 and 11 PC When It’s Idle

Ever forget to turn off your computer and come back to a screen you thought you left hours ago? You’re not alone. Leaving a PC running when it’s not needed wastes energy and can shorten the life of your hardware. Luckily, Windows 10 and 11 let you automatically shut down your computer when it’s been idle for a set period. Here’s how to set it up, step by step.

Why Set Up Automatic Shutdown?

• Save Energy: Cut down on electricity bills.
• Protect Hardware: Less wear and tear.
• Security: Reduce risks if you leave your PC unattended.

Method 1: Using Task Scheduler

Windows Task Scheduler is the best built-in way to automatically shut down your PC after it’s idle.

Step-by-Step Instructions

1. Open Task Scheduler

• Press Windows Key + S and type “Task Scheduler.”
• Open it.

2. Create a New Task

• In the right pane, click Create Task.

3. General Settings

• Name it something like “Auto Shutdown When Idle.”
• Select “Run whether user is logged on or not.”
• Check “Run with highest privileges.”

4. Triggers Tab

• Click New.
• Begin the task: On idle.
• Click OK.

5. Actions Tab

• Click New.
• Action: Start a program
• Program/script: Type shutdown
• Add arguments: /s /f /t 0
  (This forces shutdown immediately. /s = shutdown, /f = force close apps, /t 0 = zero-second delay.)
• Click OK.

6. Conditions Tab

• Optionally, you can tweak “Idle” settings here for more control.

7. Finish and Save

• Click OK.
• Enter your Windows password if prompted.

That’s it! Now your PC will shut down automatically when it’s idle.

Method 2: Using a Simple Batch File (Advanced)

If you want a bit more control, you can set up a batch file to check idle time and schedule a shutdown.

1. Open Notepad and Paste This Script:

@echo off
set idle=60
for /f "skip=1" %%i in ('"wmic path Win32_OperatingSystem get LastBootUpTime"') do set lastboot=%%i
for /f "tokens=1" %%a in ('"powershell -command "& { (Get-IdleTime).TotalMinutes }" "') do set idletime=%%a
if %idletime% geq %idle% shutdown /s /f /t 0

• Save as idle_shutdown.bat.
• Change set idle=60 to however many idle minutes you want.

2. Schedule This Batch File Using Task Scheduler

• Create a new task that runs this script every so often (e.g., every 15 minutes).

Notes

• If you only want the PC to shut down when no one is logged in, set that condition in Task Scheduler.
• Want to log off instead of shut down? Change the action’s argument to /l.
• If you use your PC for downloads or long-running tasks, set a longer idle period or exclude those scenarios.

Final Thoughts

Setting up automatic shutdown on idle is straightforward and pays off over time. You don’t need extra software—Windows has what you need built in. Get it set up, and your computer will take care of itself, even when you forget.
