I'm no programmer nor coder or such, I call myself advanced user only.

If having part of an app (I refer app as OS here, and start menu as part of an OS) to spike CPU/memory usage, does that means that part is not being used without being called? and leaves resources fully free? Sure big spike happen when the sub-part is called, but without being called?

IF part of an app is not even loaded while not used, isn't that actually good? I mean, depends how often that app part is called and have to load from the void.

I imagine that could be better than having unused part loaded all the time, wasting the resources?

Also, I totally skip part of poorly coded compared to old smooth and optimized code.

Switched to windows 10 a month or so ago just for ease of use with video games and mods. Man does windows suck ass. Wants to open random web pages, use dumb AI tools and give me useless info on every empty inch of screen space . At the end of the day it works but quality of life is low.
