Windows Update keeps Windows 11 updated by automatically downloading and installing the latest updates, drivers, and hotfixes released by Microsoft.
Active hours let Windows know when you’re typically at your PC. Windows will use that info to schedule updates and restarts when you’re not using the PC.
The default active hours is 8 AM (8 on 24 hour clock) for Start time and 5 PM (17 on 24 hour clock) End time.
This tutorial will show you how to set active hours for when you use your PC to not automatically restart your Windows 11 PC during this time to finish installing a Windows Update.
