If I click No, it returns me to the Ethernet Properties sheet with the multiplexor protocol disabled. If I click Yes, it unchecks the multiplexor protocol and then closes the dialog and property sheet. The googler wasn't very helpful, here.
Uses. Hydrogen peroxide is a mild antiseptic used on the skin to prevent infection of minor cuts, scrapes, and burns. It may also be used as a mouth rinse to help remove mucus or to relieve minor mouth irritation (e.g., due to canker/ cold sores, gingivitis).
In addition to making your cuts fizz (which, by the way, has nothing to do with killing bacteria), hydrogen peroxide also hurts like [bleep] when you pour it on a wound, but not for the same reasons that alcohol does.
