There is also the situation where you need to reinstall Windows but do not want to lose your app data and settings in the process. All apps have a maximum roaming quota for instance which can block some data from being synchronized automatically. While that is easily done using the installed apps listing available in Windows Store and even means that some settings, preferences and information are synced automatically between devices, there are certain limitations to the data that is synced. If you own a second PC you may want to install a similar set of apps on it. This may be the progress in a game that you have downloaded from Windows Store, playlists in a music application or custom profiles that you have set up in a photo editing app. Apps just like many desktop programs save data to the system when they are used.
