Remove the transitional MainWindowViewModel(AppSettings, IStartupTracer) constructor and the _ownsServices flag now that every caller resolves the view model from the container; the container owns and disposes the hardware monitor (driver unload), so the view model no longer disposes it. Make HardwareMonitorService.Dispose idempotent with a _disposed guard, and run provider disposal in a finally block in MainWindow_Closed so the ring0 driver is always unloaded on real exit even if an earlier teardown step throws.
