Task Manager shows wrong process memory usage

0

I don't have much info on this one, other than it happened some time ago (can't pinpoint what could've caused it) and a reboot doesn't fix it.

Here are a couple of screenshots:

short process list in process explorer, firefox.exe has 678K working set usage

short process list in task manager, firefox.exe has 430K private working set usage

I'm completely clueless and so are the friends I asked. What could be the problem?

This can happen if you have customised your regional settings and the decimal symbol and digit grouping symbol are the same.

Go to Control Panel → Clock, Language and Region → "Change date, time or number formats", click on "Additional settings..." and make sure the two symbols are different.

This did solve my problem and I hadn't found the first time it was answered because I was looking for different keywords. Thank you for the solution and I apologize for the duplicate. – Svetlana – 2014-01-04T17:55:37.253

Working set and Private Working set are different metrics, they will not be the same.

Working set includes non private memory such as shared dlls, and will be higher for a Win32 application that uses 3rd party libraries, including ones supplied by the operating system. Private working set memory is not shared with any other applications.

I think he's referring to the fact that the figures in the memory usage columns are several orders of magnitude too small. – Indrek – 2014-01-03T07:54:38.343

well that is quite an interesting issue – Richie Frame – 2014-01-03T08:12:30.723
