Windows 10 has a useful feature that notifies you about scheduled restart times necessary to complete the installation of system updates. If you decide to enable update restart notifications in Windows 10, they will ensure you’re not taken by surprise when the system needs to reboot your computer.
When updates are downloaded and a system restart is needed to finalize the installation, Windows 10 displays a notification toast by default. More update restart notifications can be enabled starting with Windows 10 build 15019 (which will also become available in Creators Update).
How to enable update restart notifications in Windows 10
Open the Settings app and navigate to Update & Security -> Windows Update. Click on the blue ‘Restart options’ link on the right.
On the following page, toggle the switch under ‘Show more notifications’. That’s it!
Thanks to the new notification options, you can save your work and be prepared for an update restart. The old Windows behavior of nagging us with that restart prompt over and over and finally doing it automatically while we were working on something important won’t be missed.
Speaking of, while you’re on the Restart Options page, you might want to also customize the “Active Hours” feature. It’s a way to let Windows know you’re actively using the computer during these hours. This means it won’t schedule any restart or install updates during the time frame you define.
