Get-process and UserName

Question

Hi,
I'm trying to list all/some process and need to include the username since the script has to run in a terminal server environment. It works using WMI (Get-WmiObject Win32_Process and GetOwner()) but get-process provides some more attributes I need to export to  a logfile.
Accoring to MSDN there is a property called UserName in the StartInfo object, but the value is always empty, when executing this script:
get-process
outlook | select-object id, path, @{Name="UserName";Expression = {$_.StartInfo.UserName}}
What's wrong? I am fairly new to PS, so is this the correct way of reading that property?
Thanks, regards

This is fantastic.  My question is how i would take the same code but add an exclusion for the owner of the process.  ( ie: delete all *.exe processes whose owners are not equal to "string = x,y,z" or "array[x,y,z]" )
For instance.  We have an erp system that creats a *.exe file for each logged on user.  Our problem is that we have users that do not properly log off the sytem thus resulting in a hanging session and max users reached errors. 
At the current time i manually delete these sessions but would like setup an automated process to clear these sessions every evening.  There are about 12 of these sessions that we do not want to delete as they are more of a system process that we wish
to keep running.
Any help or direction would be much appreciated!
