How to Change Windows 11 Automatic Maintenance Time
Windows Automatic Maintenance (WAM) performs background tasks like security scans and app updates. By default, it runs at 2 AM. If your computer is off or in deep sleep at that time, these tasks may not finish. Changing the time ensures your PC performs system performance optimization when you are not busy but the computer is powered on.
What happens when done?
Once you change the time, Windows will wait until your chosen hour to start background tasks. If the computer is idle, it will begin maintenance. If you are using the PC, it will wait until the system is idle again to avoid slowing you down.
How to check if maintenance is running
You can see if tasks are active using Task Manager. Press Ctrl + Shift + Esc. Click the Performance tab to see CPU and Disk usage. If usage is high and you are not doing anything, maintenance might be running. You can also view the Task Scheduler library to see the status of specific background tasks.
Change Windows Automatic Maintenance Time Using Control Panel
This is the simplest way to update your schedule.
First, open the Control Panel app.
Go to Control Panel > System and Security > Security and Maintenance > Automatic Maintenance.
Click the Change maintenance settings link.
Select the specific time you want WAM to run each day.
Close the Control Panel when you are finished.
Change WAM Time Using Local Group Policy Editor
⚠️ Requires admin privileges: You can use the Local Group Policy Editor to set this schedule.
Open the Local Group Policy Editor.
Navigate through these folders: Computer Configuration > Administrative Templates > Windows Components > Maintenance Scheduler.
Double-click Automatic Maintenance Activation Boundary on the right side.
Choose Enabled and pick your new time. Save your settings and restart your computer for the changes to take effect.

Change WAM Time Using Windows Registry Editor
⚠️ Requires admin privileges: If you cannot use the Group Policy Editor, use the Windows Registry.
Go to this path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\Maintenance
Right-click in the empty space and select New > String Value. Name it Activation Boundary. Double-click it and enter your time code.
Save your changes and restart your computer.
Summary
Windows Automatic Maintenance keeps your system running smoothly. You can change the default 2 AM time using the Control Panel, Group Policy, or Registry. Always restart your computer to apply changes. Use Power settings to stop the PC from waking up if you prefer silent operation.
Why does Windows 11 maintenance run multiple times a day?
Windows runs maintenance tasks whenever the system is idle for a specific period. While the main schedule is once daily, the Task Scheduler library may trigger smaller background tasks throughout the day if the computer is not busy. This ensures your system stays updated and secure without interrupting your active work.
Does changing the maintenance time affect Windows Updates?
Yes, but only indirectly. WAM triggers the Windows Update service to check for patches. Changing the time shifts when these checks occur. For better control over updates, refer to the official Microsoft Active Hours support page to prevent restarts during your work day.
How do I stop Windows 11 from waking up for maintenance?
You can disable wake timers in your Power settings. Go to Control Panel > Hardware and Sound > Power Options > Change plan settings > Change advanced power settings. Expand Sleep, then Allow wake timers, and set it to Disable. This prevents the computer from waking up for scheduled background tasks.
