On Windows 10, optional updates are those updates that aren’t 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 and third-party drivers (such as for printers, cameras, network adapters, etc.).
In earlier releases, optional updates happened automatically, but starting with version 2003, May 2020 Update, the Settings app is getting a new section that allows you to view and decide which updates to install manually.
How to install optional updates using Settings
Use these steps to download and install optional updates on Windows 10:
Click on Update & Security.
Click on Windows Update.
Click the View optional update link.
Expand the update category, such as the Driver updates section.
Check the optional update that you want to configure.
Click the Download and install button.
Once you complete the steps, the package you selected will download and install on your device.
If you don’t see the option, it’s likely that you’re not running the version that supports this feature. The “Optional updates” settings are available starting with Windows 10 build 18980 and later.
