[sccm 2012] Deploying Appx files during Task Sequence

[DavR]

Has anyone had any experience of deploying Appx or Appxbundle files as part of a Task Sequence in SCCM?

 

I've got a couple of UWP apps that I've downloaded the offline files for and deployed successfully as Applications with SCCM via PowerShell scripts (never could get the native functions in SCCM to provision apps properly), these deploy to machines and provision for all users just fine.

 

What I've recently realised though is that two out of three are not installing correctly in my install OS task sequence. One does just fine (OneNote), one installs OK then is removed at first login(!) citing sideloading policy (Minecraft EE), and one just crashes and burns in a way I can't quite figure out (XBox Apps).

 

I've been installing my apps from PowerShell scripts using Add-AppxProvisionedPackage, although I've also tried DISM /Online /Add-ProvisionedAppxPackage with a similar lack of success. I've seen some talk of needing the registry entries HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\Appx\AllowAllTrustedApps and AllowDeploymentInSpecialProfiles enabled, but I added a script to do that and it made no difference.

 

Not sure whether to keep pursuing it, or give it up as a bad job at this point to be honest. Devices will get the apps in due course via software deployment, I'd just much rather things were ready to use from the off.
