I'm guessing it's mostly due to add-ons installed by third party software. There are APIs that let third party stuff hook into Explorer, and the current situation is an absolute shit-show. Because there are so many old and broken ones, Explorer loads them to see if they crash, and if they do it loads them again in compatibility mode, and if they still crash it gives up. Once loaded there are no limits on how slow they are to start up or operate.
