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).
One advantage of hydrogen peroxide over some other bleaching agents, such as chlorine gas, is that the decomposition products, water and oxygen, are not harmful. Hydrogen peroxide also plays a less beneficial role in modern life, as one of the causes of photochemical smog.
