Some Windows 10 users are finding that their Windows Store UWP apps take a long time to load. Yet other Windows users are finding that their Windows Store apps take forever to load, after updating their Windows 10/8.1.
When you launch a Windows Store app, you are first greeted by the splash screen, consisting of plain background color, a swirling circle, and a 620×300 sized image. Your operating system displays this screen till such a time that the opened app is fully initialized and activated. Once the app is fully initialized, the screen goes away, and you are taken to the app’s initial UI page.
By default, if this app initialization operation is delayed and a window is not displayed within a reasonable amount of time, Windows will wait for a maximum of 15 seconds, after which, the OS will simply terminate the app.
