Manages a Windows app's ability to share data between users who have installed the app. If you enable this policy, a Windows app can share app data with other instances of that app. Data is shared through the SharedLocal folder. This folder is available through the Windows.Storage API. If you disable this policy, a Windows app can't share app data with other instances of that app. If this policy was previously enabled, any previously shared app data will remain in the SharedLocal folder.
