I've seen many people that think deleting a shortcut from desktop will uninstall the app/program. The Tips app should have clear instructions for how to uninstall an app or program from Windows so people can learn quickly how to do this the proper way.
in addition to that, when someone is trying to delete a shortcut of a program or app from desktop, show a non-intrusive bubble or notification next to it to let them know deleting a shortcut won't actually uninstall/delete the program/app.
lastly, when I search for "Uninstall" in Tips app, nothing shows up. it says search in Bing instead.
