I have a problem in showing memory in task manager with memory and paging columns. Why it shows so small size usage? And maybe anyone knows how to fix it?
Here is a screenshot(working set, memory, page pool) sorted by most consuming:

See this article What do the Task Manager memory columns mean?.
You need to choose in the View menu "Select columns", which columns to display.

Memory - Working Set:
Amount of memory in the private working set plus the amount of memory the process is using that can be shared by other processes.
This is an ancient post, and there's not a lot of information here, but we can see that despite all those small working sets the physical memory usage is high, at a total of 87%. Because of the small amount of available RAM, Windows has probably shrunk process working sets as much as it can to make room for something else - possibly nonpaged pool, which is possibly being leaked by some driver. This does not show up in any process working set. The next things to look at would be the Task Manager's "Performance" tab and the sysinternals tool RAMmap. If it is a nonpaged pool issue, Poolmon will often let you find the offending driver. If it isn't, or if Poolmon isn't helpful, then the Windows Performance Toolkit is the next thing to try.
