When you install an MSIX package that has a service as a standard user, the UAC popup requesting permission labels the program needing permission as "Unknown Program".  'nuff said.

I had this issue a few weeks ago, but a few days later after I got the prompt, when I was about to file a bug with MSFT I couldn't reproduce it anymore :(. I didn't spend more time hunting it down.

Maybe you need some OS updates?

 

What was even worse is that the prompt had a field called "Verified Publisher" which listed Microsoft as the publisher of the package I built and signed with a test certificate. (Probably because the publisher information was extracted from the app installer OS client, and not from the package - see attachment)

 

 

I am seeing this on insider build 210320 today. I'll have to go back and check if this is just the preview appinstaller or if this also exists on 20H2.
