How can I record audio to wav format?
When I use Voice Recorder, it always saves it as a .m4a, but I need the file as a .wav.
I know it is possible using Sound Recorder in Windows 7, but Windows 10 seems to use a different program.
Is there a way of doing this natively in Windows 10?
Any particular reason you want to do this natively? Otherwise I can recommend Audacity. It allows you to record audio files among others. The option to save to wav is found in the file/export audio menu. Furthermore Audacity is free software, so that should not keep you from using it.
