PowerShell - Memory usage per user

From time to time you might need to find out which user to logoff from a server because of low memory.

instead of looking at the Task Manager and trying to find who is using the most, you can use this PowerShell script:

$h = @{}
get-wmiobject win32_process | foreach {
    $u = $_.getowner().user;
    if ( $u -ne $null)
    {
        if ( !$h.ContainsKey($u) )
        {
            $h.add( $u, $_.WS);
        }
        else
        {
            $h.item($u) = $h.item($u) + $_.WS;
        }
    }
}
$h.GetEnumerator() | sort value -desc

Notice that this gives you the actual RAM usage which might not be what you are looking for, as recent users probably using more RAM than not recent ones.

If you want to know the total usage of Virtual Memory - replace "WS" with "VM".

Anonymous said...: I'm sending a new change to show the memory in MB:

$h = @{}
get-wmiobject win32_process | foreach {
    $u = $_.getowner().user;
    if ( $u -ne $null)
    {
        if ( !$h.ContainsKey($u) )
        {
            $h.add( $u, $_.WS);
        }
        else
        {
            $h.item($u) = $h.item($u) + $_.WS;
        }
    }
}
$h.GetEnumerator() | select-object name,@{name='MemoryUsage';expression={$_.value/1mB}}|sort name; February 12, 2021 at 8:40 PM
