Turned of f the circuit breaker to the microwave. Unscrewed the cover (1 screw!) popped out the old bulbs and plugged in the new ones, using the bubblewrap as a handle to be sure my skin didn't touch the light bulbs so the oil from my hands didn't damage or shorten the life of the new bulbs. Turned the circuit back on. That's it!
