I gave tune up as a general example. I don’t know which processes are triggering this.

You could temporarily disable those startup programs (and there are many simple portable GUI tools to do it) and reboot. After the reboot, review the memory usage, and repeat the review 10/20/30 minutes after that, so you can have some kind of stable conclusion of several values. For every memory review, all other tools / programs should be completely closed, or the comparison wouldn’t be useful for this case.
