+<!--Description-->
+This policy setting determines whether Windows supports web-to-app linking with app URI handlers.
+
+Enabling this policy setting enables web-to-app linking so that apps can be launched with a http(s) URI.
+
+Disabling this policy disables web-to-app linking and http(s) URIs will be opened in the default browser instead of launching the associated app.
+
+If you do not configure this policy setting, the default behavior depends on the Windows edition. Changes to this policy take effect on reboot.
