Windows 10: Why is my laptop using 70% memory idling?

A lot of applications appear to be using memory in task manager, but I have nothing running and when I try to end a task, they appear again taking up memory. This has never been a problem before. I'm running Windows 11.

Extremely high idle memory usage

Here is your first step:

1- Open Task Manager to the Processes tab and look at the Memory column.

2- What process(es) are using so much of your memory?

 

Memory use shoots up to 99% after idle time

I'm facing this problem in the last few days. Memory use according to Task Manager goes up to 99%, CPU reaches 80% and the PC becomes almost totally unresponsive.

Based on similar threads I installed RAMMap and here's what is shown.




I installed Poolmon and ran it and this is what I get.




Please note that the first entry does not show a tag. Is this normal?

According to the rest of the listing I should investigate Volsnap.sys and atc.sys. Could you advise what are the next steps?

 

My Memory usage is unusually high when idle.

My laptop memory usage improved a bit when I updated to Windows 10 ver 2004 (coming from 1909). My memory usage in 1909 when idle is around 70-80% and then when I updated to 2004 it became around 55-80%, I would like to know if any of you can give me tips
or a step-by-step instruction on how to reduce memory usage. I will attach the images below. This was bothering me because I can't browse chrome normally (for ex: receiving "not responding errors" randomly.
