With the move to the DCHU driver model many of the typical tray applications have migrated to a Universal Windows Platform (UWP) application. These applications are typically installed from the Windows Store into a specific user profile. However, in environments where the Windows Store is blocked or IT needs to deploy these applications as part of a bare metal OS deployment task, a different installation method is required. HP is introducing UWP application pack that is designed to complement the HP platform driver pack to make OS deployment easier for IT administrators.
