On Windows 10, optional updates are those updates that are not critical to use the operating system, but they may be necessary for other functionalities. Usually, these updates can include packages for Microsoft and non-Microsoft products, feature updates, and third-party drivers (such as for printers, cameras, and network adapters).
In earlier releases, optional updates happen automatically, but starting with version 2004, May 2020 Update, the Settings app is getting a new section that allows you to view and decide which updates to install manually.
Install optional updates using Settings
To download and install optional updates, use these steps:
Open Settings on Windows 10.
Click on Update & Security.
Click on Windows Update.
Click the View optional update link (if available).
Expand the update category. For example, Driver updates.
Check the optional update that you want to download.
Click the Download and install button.
Once you complete the steps, the package you selected will download and install on your device.
The “View optional updates” option is only available if the system detects an update is available. Otherwise, the option will not appear in the Settings app. Also, starting with update KB4566782, Device Manager no longer includes the option to download driver updates. If you have problems with a piece of hardware, you can now have to check for updates in the “Optional updates” page.
