If you could download RAM, would you?
I do remember having a tool that helped clear unused ram way back in the early 2000's. It did seem to work for leaky programs.
No but I would download a car.
I have an i3 laptop as my daily that I bought over a decade ago. It runs Niggerball games I like to this day.
I think operating systems minus bloat are optimized big time nowadays. Might have been different in the pre XP days.
I keep a old laptop around for random basic stuff. No reason to get rid of it. Its light, it was cheap and it does what is needed.
Until it doesn’t work, it works. I don’t mind buying a new battery every couple years.
