Visual Studio - Is there any way to make the "Output" and "Error List" windows not appear after a debugging session?

It just occurred to me, after years of closing these two windows after a debugging session, that there may be a way to turn them off. I generally have the output window open while debugging and only check the error list periodically for warnings, and can always get to them if I want them anyway. Hoping someone else may know of a way to stop the default behavior?
