Install Windows updates

To have Windows install important updates as they become available, turn on automatic updating. Important updates provide significant benefits, such as improved security and reliability. You can also set Windows to automatically install recommended updates, which can address non-critical problems and help enhance your computing experience. Optional updates are not downloaded or installed automatically. To learn more about the types of updates that Microsoft publishes, see this Knowledge Base article on the Microsoft Help and Support website.

If you do not turn on automatic updating, make sure that you check for updates regularly. For more information, see Turn automatic updating on or off and Change how Windows installs or notifies you about updates.
