### Remarks

Windows uses URI schemes to launch the application when the user clicks hyperlinks that match the URI scheme. If you register the application as a URI scheme handler, then it also [handles URI activation events](https://docs.microsoft.com/en-us/windows/uwp/launch-resume/handle-uri-activation#step-3-handle-the-activated-event). In the Editor, Unity displays this under **File and Protocol Associations** in [UWP Player Settings](/engine/6000.6/manual/platform-specific/windows-store/uwp-getting-started/class-player-settings-wsa.md). For information on Windows URI activation, see [Microsoft's documentation](https://docs.microsoft.com/en-us/windows/uwp/launch-resume/launch-app-with-uri).
