Where can I find "show process from all users" for WIndows 8.1 Task Manager?

It might be a very simple answer. I use Windows 8 64bit machine and it is running out of memory. I tried to figure it out, but It doesn't say which programs are consuming  the memory. I run Task Manager as Administrator, but still I can not see all processes running on my Machine.

Is there any services taking more resource ?
Since your system will have UAC on,you will have to run taskmgr elevated. Then, all are seen on the details tab.

Thank you for the reply.

My machine's memory constantly spikes 70 ~ 90% and I'm trying to figure out which background services are using resources. In Task bar, Users tab, I only used 2GB of memory (I have 8GB memory on my laptop), but shows 80% for example. I do have 2 Hyper-V clients, they are not active now.

I have an administrator right on my computer also, I tried run Task Manager as different user (administrator), but I can not view system or other users are running resource intensive applications.

Create a reliable backup. Make sure you always have dependable copies of your data so you can restore your entire system or individual files.

Are you looking at the "Details" tab (4th tab)?
Also make sure that you show the max. workingset column to see which process requested a lot of memory though not having it in use now.

Here are some W8 screenshots that may help:

W8 TaskMgr More details
Above is the first TaskMgr screen. Click More details and this will come up, with the Processes tab selected:

W8 TaskMgr Processes tab
The column headers are sort toggles — first click sorts it ascending, second click sorts it descending. Click the Memory header so it is sorted descending and you'll see which apps are taking the most memory. Then click the Details tab and this will come up:

W8 TaskMgr Details tab
Once again, the column headers are sort toggles. Click the Memory (private working set) header so it is sorted descending and you'll see which processes are taking the most memory. Regards, Joe

Thank you for nice screen shots and explanation. I took screenshots that might explain my situations.

Before I asked this question, I googled alot, but could not find any answer.I am getting to think this might be a memory leak or system issue since other people don't have problem finding it. Something still is taking memory ,but could not find that...

<Performance Tab>
About 6.0GB used.
<Details Tab>
These not adding up to 6GB!
3 GB of memory resources are gone...

Hi Kim,
I think the answer is right there in the Details tab. For starters, half a gig is going to Remote Desktop. Then you have a large number of tabs open in Chrome, with each tab taking memory — the visible portion shows about 1.5GB for Chrome processes, but eyeballing the size of the dark gray portion of the vertical scroll bar says that it's showing only 15% or so of the items. Of course, it's sorted descending, so the ones lower down are smaller, but there's a lot of them, so they could add up to a big number.

One other idea — try Process Explorer:

It's a fantastic tool that shows more details than Task Manager. It also has Save and Save As menu picks that will write all of the process details to a text file, making it easier to analyze. For example, you could copy paste the Working Set sizes into an Excel spreadsheet. Also, to get all processes, click File>Show Details for All Processes. Regards, Joe

Thank you for the reply.
I tried Process Explorer, but as I initially stated, I still find the gaps between inUse memory usage and  calculated memory usage.. I downloaded Process Explorer and exported the Process explorer data to the txt file, then sum the total memory usage. The following is the finding:

Memory In use 3.4 GB (just a bit later after the reboot. I uninstalled Chrome for testing).
Total Working Set 1,65GB.. Still can not find

I also ran memory diagnostic, but no error found.. hmm.

See if RAMMap helps:

One of the authors, Mark Russinovich, is the same person who did Process Explorer.

"I still find the gaps between inUse memory usage and  calculated memory usage..." - guess what: we all do. You will not find anyone here that will be able to sum up all the columns and get the correct amount. That's perfectly normal.
Given the fact that you seem to have a massive load of tabs open and knowing that ALL browsers eat memory like hell and also many websites make the browsers leak memory, no wonder that a good part of your 8 GB gets consumed.

Thank you! Nice tool! Total memory usages and actual memory usages in Task manager are matching. The culprits were "Driver locked" files and "Mapped File" behind high memory usage. Probably VM related, but I could dig deeper from here.
