Where is memory leaking in Windows 7?

Question

Windows

Task Manager, Performance tab, System group, Selected.
First ****/6914, then the second number grows, grows, grows. Have to reload. I did not find this memory in the processes. Closed programs.
Addition. Processes don't use much memory, and Firefox and others have shut down.
The resource monitor does not show what is in the swap file or in memory in general (RAM and swap file).
Windows reported that the memory was low, it was necessary to close programs when the second number reached 13 or somewhere there.
Addendum 2.After a while, he writes "Low memory, close programs." Close programs that take up a lot of memory. "Show all users" looked. And after that there is something like "Allocated (GB) 10/13". The size of the paging file is at the choice of the system.
Question : what are these 10 GB occupied with?
Addendum 3 . Firefox does not release memory when closing tabs. You have to restart Firefox. Perhaps Windows also does not free memory or something else. And you have to reload.

Answer 1

grows, grows. Have to reload.

What for?
You can see in more detail what memory is occupied.
In the task manager, the "performance" tab, there is a "resource monitor" button.

Answer 2

Did Windows tell you that it doesn't have enough memory? Not? Maybe some software swears? Also no? Then do not interfere with the computer to work!

Answer 3

First ****/6914, then the second number grows, grows, grows.

The second number is the total memory size. Physical memory plus swap file.
If the number grows, then there is not enough physical memory and you have to increase the paging file.
Well, considering that you have the second digit - 6914, physically RAM there is most likely 4GB - well, I think it’s clear what will be missed, and you will have to use the swap file.
Conclusion - add memory.
