Progressive web app (PWA) is an application designed to be delivered via the web without installing executables on the computer. Chrome and Microsoft Edge browsers have added the ability to automatically launch your favorite PWA when you log in to Windows 10. Users need to enable an experimental flag in Google Chrome or Microsoft Edge to enable this feature. A shortcut to the PWA will be added to users’ Windows 10 Startup folder, as shown below. The browser will then show a prompt that you need to relaunch the browser for the setting to take effect.
