How to Set Active Hours for Windows 11

Windows 11 keeps your computer safe by downloading updates in the background. Sometimes, these updates need a restart to finish. If your computer restarts while you are working, it can be very annoying. You can use Windows 11 active hours to tell your computer when you are busy. Windows will then avoid restarting during those times.

Why use Active Hours?

Setting active hours ensures your computer does not reboot in the middle of an important project. It keeps your work smooth while still keeping your system secure.

What happens when done?

Once you set these hours, Windows will treat that time as ‘busy.’ It will wait until outside of those hours to perform any necessary restarts for updates.

Option One: Set Active Hours in Settings

1. Open Settings (press Win+I).
2. Click Windows Update on the left, then click Advanced options. Open Advanced options settings

3. Click Active hours to expand the menu.
4. Choose Automatically or Manually from the drop-down menu.
5. If you choose Manually, pick your preferred start and end times, then click the check mark to save.

Troubleshooting: Why Windows 11 Ignores Active Hours

Sometimes Windows might still restart. This usually happens if you have a pending update that is marked as ‘critical’ or if you have not restarted in a long time. Ensure your Windows Update Service is running correctly in the Services app. If you are on a metered connection, Windows may pause updates entirely.

Windows 11 Pro vs Home Limitations

Windows 11 Home users have fewer options for controlling updates. Pro, Enterprise, and Education users can use the Group Policy Object (GPO) to enforce stricter restart policies. Home users are mostly limited to the standard Settings menu.

Option Two: Set Active Hours in Registry Editor

Note: This requires administrator privileges.

1. Open Registry Editor (regedit.exe).
2. Go to: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsUpdate\UX\Settings

Modify SmartActiveHoursState to 0 for manual or 1 for automatic. Adjust ActiveHoursStart and ActiveHoursEnd using decimal values in 24-hour format.

Option Three: Set Active Hours via Local Group Policy

Note: Requires administrator privileges. Only for Pro/Enterprise/Education.

1. Open Local Group Policy Editor (gpedit.msc).
2. Navigate to: Computer Configuration\Administrative Templates\Windows Components\Windows Update\Manage end user experience

3. Double-click Turn off auto-restart for updates during active hours.
4. Select Enabled to set your custom times.

Summary

Active hours prevent unexpected restarts. You can set them via Settings, Registry, or GPO. If you face issues, check your Windows Update Service status or your metered connection settings.
