All answers I could quickly find on this topic involve either the tip Molly gave or using an application (or coding it yourself). For example (I haven't tried this), Close All Windows.

Delete :) Also the pin in the top right of each window keeps that window open when you press delete in case you don't want rid of all of them. Edit: also also, control + clicking the pin means that window will always open pinned by default - useful for things like transparency options that you may always want pinned. More on reddit.com
