I've been running into a problem with many of the Windows 7 and Windows 10 workstations that I service lately. They're running out of physical memory according to the task manager. But, when you add up all memory used for the processes shown, they don't add up to the memory used. I've done some research on the problem and see that there are various types of memory leaks but I'm not sure how to detect this one or even where to start to know what type of memory leak it is. Is there a simple way (or application) to diagnose this problem? Thanks for your time!
