I am using the Unified Write Filter for a Windows 10 Embedded Application. I would like to be able to run a .msi installer to update software on the device by putting the device into servicing mode and modifying the UwfServicingMasterScript to run the installer when it is in servicing mode. In order to modify this file I need to have TrustedInstaller permissions. Is this some permission level that cannot actually be obtained or can I gain this level through an installer that has the proper chain of trust?
