Hi @Kenny Roy E ,
Welcome to Microsoft Q&A!
According to your scenario, it is recommended that you use Desktop Bridge in UWP to start a win32 desktop application and let this desktop app (such as WPF) to gather hardware, network, and software information, modify the registry, and execute PowerShell commands in background.
It will package your UWP and WPF app together, and realize communication between UWP and WPF through Appservice. For more details, you can search Stefan Wick's blog “UWP with Desktop Extension” in your browser.
Thank you.
