We've recently done a 8.1 pro build for 1300 tablets that we've basically stripped all the ModernUI apps from. We've had to get PC Settings back in order to allow PIN logon which we've succeeded in however I now, for various reasons, need to get the OneDrive app back (not just the icon in the notification area). I presume there must be an 'add-appxpackage' option but I can seem to find the package name for OneDrive. Does anyone have any idea?
