To be honest I use my microwave oven only to heat stuff! I never use it for cooking. Also I've never used any of those menus in it that says cooking, thawing and much more.
What all do you do with your microwave oven.
Of course I also use the microwave oven to heat the food. But I also use it to cook something like potatoes and pumpkins. As it is easier to cook them with the microwave oven. It just spends a few minutes.
