How can I check the virtual memory occupied by a process?

I have a computer that often prompts that the virtual memory is insufficient, but the memory usage is normal. The virtual memory usage is obviously too large. I want to check what processes are occupied and what method is the easiest to use? Not to mention that I set the virtual memory too low. Although it is the default value of the system, it will not be too low. Besides, I also know how to set it. I just want to know what process occupies the virtual memory. Is there a solution? Do I need software?

In the task manager, how does one know which process occupies the memory and close this program?

Right-click the blank area in the taskbar (blue bar below the screen)
Select Task Manager
In the displayed dialog box, click Process
