ELI5: Why do some Windows Updates need up to 1 hour to install, even longer than the first installation of the OS itself?

Generally these large updates are essentially new versions of the OS, with one big exception. When you first installed the OS the computer was blank, so it was rather easy for the computer to just plop everything down and be done. Now since this is an update the computer also has to worry about making sure your setting stay the same, your files aren’t deleted, etc. which slows things down and makes it take extra time.
