It is important to regularly update Windows 10. Updates include security improvements, bug fixes in Windows, and sometimes new features.
Windows 10 updates are usually already installed automatically on a regular basis. But sometimes it is useful to check for a new update yourself and have it installed. This is useful, for example, if you notice that your computer is not working properly. A Windows update can sometimes solve the problem.
After installing the update, the computer usually needs to be restarted. That can be immediately or later. Upon reboot, the update will be permanently installed and activated. Make sure to save open files and close open programs before updating. And never turn off the computer during the update reboot.
Update operating times
If you choose to restart your computer later after installing a Windows update, Windows 10 will take the usage times into account. These are the times between which you usually use the computer. You can set these usage times yourself, so that Windows only restarts after that time to install an update.
