Hi Vswiowo Ywusuys,
Thanks for your post. Generally speaking, you can use Group Policy settings, mobile device management (MDM), or Registry (not recommended) to configure when devices will restart after a Windows update is installed. You can schedule update installation and set policies for restart, configure active hours for when restarts won't occur, or you can do both. Active hours identify the period of time when you expect the device to be in use. Automatic restarts after an update occur outside of the active hours. By default, active hours are from 8 AM to 5 PM on PCs and from 5 AM to 11 PM on phones. Users can change the active hours manually. Starting with Windows 10, version 1703, you can also specify the max active hours range. The specified range is counted from the active hours start time. Administrators can use multiple ways to set active hours for managed devices:
- You can use Group Policy, as described in the procedure that follows.
- You can use MDM, as described in Configuring active hours with MDM.
- While not recommended, you can also configure active hours, as described in Configuring active hours through Registry.
