2024-08-27 15:31 AEST by Arthur Barrett - Would be good to have a 'systems setting app' to replace the control panel.

But documentation on how to do this seems scarce.  Here is someone asking 5.5 years ago:
https://stackoverflow.com/q/53619535

But I did find some documentation.

It needs to be a UWP app.  For device drivers which need a corresponding settings page, the instructions are 
here:

application

What I don't understand is the distinction between Windows 7 and Windows 8 compatibility.

This implies that a systems setting app written specifically for Windows 8 can still appear in the Windows 10 
systems setting app, but not support any of the new features, but not a systems setting app written for 
Windows 7.

Also it look like Microsoft are moving away from UWP to Windows App SDK (requires Windows 10 version 
1809, Windows 11, Windows Server 2019, Windows Server 2022):
