when i press ctrl-alt-del and open Task manager I see that Memory is used at 80% (Performance tab), but if I add all the memory usage values for each program from the Processes tabs there's no way it adds up to 80% ! How can I see the real memory usage for each app?

PS: I found that view... select columns let's me show more data. So I checked all memory columns and the only one that could reach that 80% value is "Peak working set". There the values are much higher and I see a huge 2.5 GB usage from "svchost". But svchost is some kind of library, how can I see what program makes it use so much?

Here's a screenshot to see what I mean:

Task Manager

Total RAM is 8 GB and usage is always at 6 GB +

PPS:

closing virtualbox freed a lot of RAM, down to 50%, but why doesn't the virtualbox real ram usage show up in task manager?

    I use Process Explorer from Microsoft. To measure ACTUAL usage of physical ram, look at the Private Working Set (aka WS Private) metric. you will have to add a column to see it in the main grid. See my comments here for a description of what the different memory statuses measure: http://superuser.com/questions/618686/private-bytes-vs-working-set-in-process-explorer – Frank Thomas Jan 21 '16 at 03:21

    Peak Working Set is the highest value used during the process lifetime. So it's most likely not what you're looking for. – Daniel B Jan 21 '16 at 05:53
  • is your question answered? Do you need more help? – magicandre1981 Jan 30 '16 at 08:20

The svchost.exe is a container to start Windows services. Windows 7 has a bug, which causes a large memory usage of the WindowsUpdate service. Microsoft fixed it in several Windows Update Client updates. Install the latest one from December 2015 to fix the memory usage.

For a detailed memory usage overview, always use RAMMap.
