What is the Fastest Way to Apply Windows Updates?

For some reason Windows 10 updates seem to always happen at an extremely slow speed. I have several computers and this seems to be the case on all of them. When I look at task manager all graphs are low and there seems to be no obvious bottleneck. It’s as if there was some sort of artificial limit/throttling that limits the speed at which the updates happen. Is there a way to control the limit? Alternatively is there a way to trick Windows to raising the limit? Would locking the screen trick Windows to use more power on applying the updates? Do the updates get applied faster or slower if I have the Windows Update window open?
