The consequence of these leaks is a big drain on physical PC resources that can cause RuntimeBroker to use many gigs of memory. Linked with these leaks are third-party application that implements a Live Tile update function known as “TileUpdater.GetScheduledTileNotifications.” When the tile update executes, Windows shares the request, but never actually launch the memory linked with the function.

You must note that every update call uses a small amount of memory. However, the effect snowballs are repeatedly shared and the memory can’t get reallocated. If you want to resolve the issue it needs the developer of the app to modify how the Live Tile updates work for the specific app with the leak. As an end-user, the only choice is to ignore using any apps with memory leaks, and wait until it becomes updated.
