One piece of super useful software that I thought I'd share is SoundSwitch, which I use to switch the audio between my speakers and gaming headset with a keyboard shortcut.
Prior to this I kept plugging/unplugging my gaming headset everytime I wanted to switch devices, or I'd dig through Windows menus to change the default audio device. Super annoying.
Enter SoundSwitch, I can configure profiles and switch between them with a keyboard shortcut.

I have no affiliation, I just thought I'd share something useful that I've recently started using.
