The script works when I run it manualy (comment out the snapin) but I see some authentication errors on the cli. Most notably the "Get-WmiObject : Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESS DENIED))" error. However the CSV populates with all the information as if there was no error at all. We would like to have this running on a scheduler for our patch dates. I am just wondering if the errors that showup in powerCLI will prevent a scheduled task from completing? Also is there a way to correct these issues we are running the script as a user that has local admin rights on the servers the script checks. I have tried -authentication 6 -enableallprivaleges and a host of other googled answers. None of them have corrected the issue. However its baffling as it still returns the correct information.

Is there a better way to do this? Is there a cleaner way to code the script? Last question is there a way to change the output of "Get-WmiObject Win32_QuickFixEngineering -ComputerName $row.Name | ? { $_.InstalledOn } | sort installedon | select -Last 1 #| ft hotfixid, installedon" from "

\\Server\root\cimv2:Win32_QuickFixEngineering.HotFixID="KB2624667",ServicePackInEffect="SP3" to something a little more readable like "Last Patch = KB2624667"? We do not need the service pack information.

I have cobbled this together from many other scripts into a workable script that does what we want I am just wondering if there is a way to clean it up. Thank you for looking and taking the time to respond.
