If you've ever tried to record streaming audio in Windows, like a Skype call or a webcast, you may be aware of a simple setting that allows you to record any sound playing through your computer's sound card. All you have to do is:

Select sound from the control panel.

Select the recording tab.

Right click on the background of the tab and choose "show disabled devices."

Right click on Wave Out Mix and click enable.

Now it should work the same way as Wave Out Mix in Windows XP, allowing you to record any sound your computer makes.
