How to Schedule Automatic Maintenance on Windows 11
Windows 11 has a built-in feature that keeps your computer running smoothly. It handles tasks like security scans and updates in the background. By default, this happens at 2 AM. If your computer is off at that time, Windows will run these tasks the next time you are not using your PC.
Why use Automatic Maintenance?
Computers collect temporary files and need regular updates to stay safe. Automatic Maintenance gathers these chores into one scheduled time. This keeps your system fast and secure without you needing to do anything manually.
What happens when done?
Once the maintenance is complete, your system will be updated, scanned for threats, and cleaned of temporary clutter. This ensures your computer runs at its best speed.
How to change the maintenance time
If your computer is usually off at 2 AM, you can pick a different time when your PC is turned on. You must have administrator privileges to perform these steps.
- Open the Control Panel Control Panel. You can find this by clicking the Start button and typing “Control Panel.”

- Go to System and Security, then click on Security and Maintenance.

- Click the small arrow to expand the Maintenance section.
- Click the link that says Change maintenance settings.

- Pick the time you want the tasks to run.
- Click OK to save your settings.

You cannot turn this feature off completely, and it is best to leave it on. It is designed to keep your machine healthy.
Summary
Automatic Maintenance is a helpful tool that performs system updates and security checks for you. By setting the schedule to a time when your computer is powered on, you ensure that your system stays fast and safe without interrupting your work. Keeping this feature active is the easiest way to maintain a healthy Windows 11 PC.

The Box that needs checking is greyed out. I cannot activate this.
The check box “Allow scheduled maintenance to wake up my computer…” IS USELESS.
It will wake up regardless, at least on DELL Precision Laptop.
Same for me on a thinkpad. Did you ever find a solution?
