8.1 update load and install time: why is it going so slow & taking forever?

When I first bought my Lenovo Yoga 13 and I installed windows 8.1 it ran super quickly…2 years later, it is taking forever to load onto my laptop. Is it just because it's getting old or is there something up with Windows itself?

Added (1). When I go to my Settings, the update will be doing its thing and loading but it'll stop and freeze right in the middle of things and then start over when it never did this before. What gives?! Is my laptop just getting old or is Windows becoming outdated and super slow because of time passing? It's frustrating.

Check your start up programs. Open the Task Manager and go to the Start Up Tab.
too many start up items will cause this problem.

Restore factory setting and disable updates, since apparently it is a known bug for your laptop
