Windows Update keeps Windows 10 updated by downloading and installing the latest updates, drivers, and hotfixes released by Microsoft.
Starting with Windows 10 Insider Preview Build 14316, you can now set the time in which you are most active on your device by adjusting active hours. Active hours lets Windows know when you usually use this device. When a restart is necessary to finish installing an update, Windows won’t automatically restart your device during active hours.
This tutorial will show you how to enable or disable the active hours feature of Windows Update in Windows 10.
