Displaying results where count equals value - powershell

Question

I want to identify the top few processes by average CPU usage over a period of couple of seconds. Each result needs to list the PID, Process Name and UserID.
The script needs to be run on several servers at the same time that are in another domain. The credentials for those servers are different to the computer it is being run from.
I can’t get Get-Process to work as it doesn’t accept the –credentials parameter.
Invoke-Command will not work as scripting is restricted on these servers.
What I’ve ended up with in $TopProcess is:
User Name CPU ID Description
--------- --- -- -----------
User73 25 68680 App89.exe
User73 25 68888 App57.exe
LOCAL SERVICE 2.5 63868 WmiPrvSE.exe
User48 0 66308 App38.exe
User48 0 62608 App54.exe
User73 25 68888 App57.exe
User73 25 68680 App89.exe
LOCAL SERVICE 2.5 63868 WmiPrvSE.exe
User48 0 59336 dwm.exe
User48 0 52528 App57.exe
User73 25 68888 App57.exe
User73 25 68680 App89.exe
User39 19.5 48792 App43.exe
User39 2.5 65996 App48.exe
LOCAL SERVICE 2.5 63868 WmiPrvSE.exe
but I need to list only the results that have a CPU over 15 and are listed three times but only to list each once and
$Result = $TopProcess | Where {$_.CPU -gt $Threshold} | Measure | Where {$_.Count -eq $NoRS}
returns nothing.

Answer 1

Use the Group-Object cmdlet instead of Measure to group your result. I think you only want to get the UserName property:
$Result = $TopProcess |
Where {$_.CPU -gt $Threshold} |
group 'User Name' |
Where Count -eq $NoRS |
select Name
