Displaying the most RAM-intensive processes

It is possible to find the processes that consume the most resources without going through the task manager. This piece of code can be very useful for monitoring purposes. Here, only the 10 most greedy processes are displayed (select -first 10), but it is of course possible to modify this variable.

get-wmiobject WIN32_PROCESS |
Sort-Object -Property ws -Descending|
select -first 10|
Select processname, @{Name="Mem Usage(MB)";Expression={[math]::round($_.ws / 1mb)}},@{Name="ProcessID";Expression={[String]$_.ProcessID}},@{Name="UserID";Expression={$_.getowner().user}}
