Native Access wipes out the Windows Control Panel content when I uninstall the plugins straight from the Native Access app.
I was able to reproduce the effect by reinstalling the plugins and uninstall the plugins from the Native Access app.
As you can see (Time & Date), This is my main computer for NI & Vienna. I still have some to uninstall still but they are not showing up in the Control Panel and other apps not related are not showing either.
You can see Vienna is installed but not showing up in Control Panel anymore.
