Although Windows 10 has been improving with the implementation of Active Hours and updated logic to prevent sudden reboots to apply updates, unexpected restarts is still a problem as having to constantly remember to change your active hours as your schedule shifts can be yet another challenge.
However, starting with the April 2019 Update, version 1903, Windows 10 includes a new feature that allows the system to adjust your active hours based on your device activity automatically. However, you have to enable the feature before you can benefit from it.
How to enable automatic Active Hours using Settings
To allow Windows 10 adjust your active hours automatically, use these steps:
Click on Update & Security.
Click on Windows Update.
Click the Change active hours button.
Turn on the Adjust active hours for this device based on activity toggle switch.
Once you’ve completed the steps, Windows 10 will set a time range based on your device usage automatically, which will prevent the system from rebooting to install updates while you’re actively working.
The ability to set your active hours manually isn’t going away, you just need to disable the automatic option, and then click the Change option while you’re in the Change active hours settings page to change the settings.
If you don’t see this feature, it’s because you’re not running the version of Windows 10 that includes this setting. The ability to allow the system to adjust your active hours manually is available starting with version 1903, April 2019 Update, and newer versions.
