So far, I successfully made a UWP host app calling winrt runtimeclass method into a non-elvated (normal full-trust) win32 server exe using oop/winrt. The server exe is launched automatically when the method is called from the UWP. And I tried, it DO have file system access.

But I want to know is it possible to go further, that the UWP launches the win32 server in admin mode, and still able to do the above?
