Win32 App Powershell 64bit registry access issue

Hi,

You could create something like this and convert it (with the msi) to a intunewin file
Just like i I did with a win32 app to disable the oobe stage (for when you don't use autopilot)

I uploaded the app just a few seconds ago,first I need to spin up a clean windows 10 test vm. I will let you know the outcome. UPDATE 14:05: The registry keys were succefully created. Of course, I skipped the msi part but I this something you could use?
