winrt: Don't use LoadLibraryA on WinRT. This removes the CM_Register_Notification code on WinRT. Note that this API _is_ available to UWP apps as of Windows 10.0.17763 (version 1809, released October 2018), according to: https://docs.microsoft.com/en-us/uwp/win32-and-com/win32-apis#apis-from-api-ms-win-devices-config-l1-1-1dll So it might be worth readding with some sort of preprocessor check for minimum targeted version, or whatever is appropriate for WinRT development.
