WMI "ASSOCIATORS OF" query ridiculously slower when running as Administrator than when running as a standard user

Never experienced anything like this before, so to you I come for help...

I'm in the process of rewriting my fork of JSThePatriot's excellent Computer Information library, and my current project is rewriting the User profiling function. One of the new features I've added in is gathering the list of groups a particular user profile belongs to, which uses an existing WMI object to run an "ASSOCIATORS OF" query targeting the specified domain and username. 

When I run the function under my own user account from within ISN/ScITE or compile it and run it via Windows Explorer, my test script collects the information in a fraction of a second. When I compile the script and Right Click -> "Run As Administrator," the script takes almost three and a half minutes to complete. It's literally the exact same code, but running under Administrator has a computed 6320x slowdown. Examining the script running in Process Monitor showed no activity during what I assume are these queries, which boggles my mind. 

If someone could tell me what I'm doing wrong, that'd be super awesome. Below is the code used, and below that is a log file that I generated to root out what in particular was causing the massive slowdown. It's worth mentioning that I'm currently running Windows 8.1 on this machine, under a user account that is part of both the Administrators and Users groups.

Many, many thanks for that link! While I can't see the link on its own being incredibly useful, it did remind me of the existence of Win32_GroupUser, which a quick Google search for yielded a wealth of information that looks to be incredibly useful. 

Once I get to my computer, I'll do some testing to see what performance is like; hopefully this should help significantly.

As an update for those who might stumble across this later on:

I haven't figured out why the Associators query runs so slowly under an Administrator account, but I did rework my queries to accomplish roughly the same task. As a warning, this method will perform more queries than you'd use otherwise, and it's likely not the fastest way to do this, but it does works properly under both a standard user and an administrator account (tested on Windows 7 and Windows 8.1).

The Win32_GroupUser class is composed of two properties, GroupComponent and PartComponent. GroupComponent is a link to the specified group, and PartComponent is a link to the specified user. Since I'm not good enough yet with my WMI-fu to just get the object at the link directly, I'm instead constructing a WMI query to find any entries that match the user I specify (identified by domain and username). Using the Win32_UserAccount object for the user I'm looking up, my query looks something like this:

Local $objGroupMaps = $objWMIService.ExecQuery("SELECT GroupComponent FROM Win32_GroupUser WHERE PartComponent=""Win32_UserAccount.Domain='" & $objItem.Domain & "',Name='" & $objItem.Name & "'""", "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)

It's worth noting you can reverse this (search by GroupComponent instead of PartComponent) so you can enumerate all users in a group.

Following that, I iterate through the list of return group mappings and run a regular expression on the GroupComponent property to extract the domain and name of the group from the map string. If all you're looking for is the domain and name of the group, you can stop here, but I want to get a little more information from the group, so I run another WMI query to get that. 

For $objGroupMap in $objGroupMaps
    $aParams = StringRegExp($groupMap.GroupComponent, "^.*?(?<=Win32_Group\.)(.*?),(.*?)$", 1)
    ; It should return only one entry, so the name $groups probably isn't the best choice, but I
    ; iterate through it like any other object collection.
    ; If anyone has a better idea what to call this, I'm all ears
    Local $groups = $objWMIService.ExecQuery("SELECT * FROM Win32_Group WHERE " & $aParams[0] & " AND " & $aParams[1], "WQL", $wbemFlagReturnImmediately + $wbemFlagForwardOnly)
    If IsObj($groups) Then 
        For $group in $groups

It's obviously not as performant as running the "ASSOCIATORS OF" query under a standard user, but execution time remains very similar when running as an administrator, which is what I want. I will admit I also had an issue with this query where on my development machine it wasn't returning the local administrator's profile information, though I think that might be an unrelated issue. Yep, completely unrelated issue.

I hope this helps somebody!

      Hi all,
      I have a bit of code that works on my old Win10 PC, that fails on my new Win10 PC, and I think the only significant difference is the version of Autoit - old PC has 3.3.12, new has 3.3.14.
      I couldn't find anything mentioned in the change logs though, so perhaps I'm wrong.
      Anyway, the code to replicate my issue is:
      Test('username', 'DOMAIN') ; THIS ERRORS: ;Test('localun', 'DOMAIN') ; THIS ERRORS: ;Test(' ', ' ') ; THIS ERRORS: ;Test('', '') ; THIS ERRORS: ;Test('localun', '') ; THIS ERRORS: ;Test('', 'DOMAIN') Func Test($un, $dom) $compName = 'PCNAME' $FullName = '.' $Description = '.' ; get the WIM object $objWMIService = ObjGet("winmgmts:\\" & $compName & "\root\cimv2") ; get default user full name and description $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") If IsObj($objAccount) Then $FullName = $objAccount.FullName $Description = $objAccount.Description EndIf ConsoleWrite($FullName & @CRLF) ConsoleWrite($Description & @CRLF) Return EndFunc  
      On my old PC this code will output just . and . for each of those line currently commented out. Which is fine.
      On my new PC any of those commented out lines of code cause an error, and the script won't even compile.
      $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") $objAccount = $objWMIService^ ERROR I'm very much a newb with the WMI stuff and objects, but it looks like the .Get property is failing when either $un or $dom aren't valid in v3.3.14, whereas in 3.3.12 the .Get would fail to return an object, which is then caught by the If statement.
      Am I on track with this? Is there some new/better way to code the example so that 3.3.14 will compile it?

      Edit: I found out from looking into the post from coffeeturtle that not all motherboards support WMI temperature reading. You have to explore the WMI namespaces for your system!
      I (stupidly) fried a computer. It was an old Zotac small form factor device that was junked at work, so I turned it into a home theater PC.
      But I had put it in my "audio rack", which has glass doors and not very good ventilation. Normally I would open the doors while it was running and I use a media remote which would hibernate the system. At some point, it woke up by itself (probably Windows Update) and did not go to sleep again. Unfortunately this happened during the summer months while I was away on a small holiday and of course the glass doors were closed.
      When I finally noticed the system was on, it was super hot and the fan was at full blast. Dead. No POST, no green light on the mainboard even with a new power supply, old mechanical laptop hard drive gives errors when connected to another device. My next home project will be to make some appropriate ventilation in the audio cabinet.
      For the replacement I bought a used HP ultra small form factor machine and decided to start working on an app to monitor the ambient temperature sensor on the motherboard and shutdown the system if needed. I used some code for smooth label updates from here (needed updating to work with latest AutoIT) and temperature conversion from here (not really needed, only if you want temperatures in something other than C).
      Maybe I will work on this some more and make it configurable with an .INI file or even storing the settings in registry, but since I probably won't I thought I'd put it up as an example of what a non-expert can do with an afternoon of coding and ideas from the community here.
      This uses an ambient temperature sensor populated on HP machines in HP-specific WMI extensions but the WMI query can easily be changed to any available sensor including CPU or GPU.
      The watchdog monitors temperature, warns with S.O.S beeping if the set point is exceeded, and either shuts down if a timeout is reached while the temperatures are high or goes back to monitoring if the temperature goes lower then the set point, and logs events to the Windows application event logs.
      The GUI it puts up is very small at the top center of the screen (very small on a 4k display anyway).
      #requireadmin because of the WMI query.
      A timer for the WMI query because of prior experience using similar functions in WinPE to get model infos from HP WMI bios extensions.
      If you play around with this, please post your fixes/improvements/changes back to this thread.
      Have fun!
      Edit: Updated to show "Unable to query temperature" if the WMI query returns a null

      In Windows 10 PowerShell, one can do this to change the metric for a NIC in Windows 10:
      Get-NetAdapter | Where-Object -FilterScript {$_.InterfaceAlias -Eq "Ethernet 2"} | Set-NetIPInterface -InterfaceMetric 2 I know I can script the above PowerShell line (and it works!), but I wanted to try something I hadn't done before after looking into jguinch's most excellent Network configuration UDF. I wanted to make use of the SetIPConnectionMetric method in the WMI classes. There is an example VBscript here but this is not for Windows 10. Using AutoIT would also give better control over capturing error return codes than with PowerShell.
      But I cannot get my script to work! The return from SetIPConnectionMetric() is 0, which would indicate success. Yet the change does not happen. I also tried WMI methods using .put_ but this fails.
      Anyone more experienced than I have ideas to make this work?

      I have code that does a WMI SQL query to find all defined printers, and I want to parse the returned object in several places.  However, after parsing it the first time, all other times fail to find any printer objects.
      Here is my test code:
      test() Func test() Local $oPrinters, $oPrinter, $err, $cnt, $oP, $query $query = "SELECT * FROM Win32_Printer" $oPrinters = doQuery($query) $err = @error LogMsg("+++: $err = " & $err & ", isObj($oPrinters) = " & IsObj($oPrinters)) If ($err == 0) Then LogMsg("FIRST LOOP") ; <=== FIRST LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") LogMsg("SECOND LOOP") ; <== SECOND LOOP $cnt = 0 $oP = $oPrinters LogMsg("+++: isObj($oP) = " & IsObj($oP)) For $oPrinter In $oP $cnt += 1 LogMsg("+++: isObj($oPrinter): " & IsObj($oPrinter) & ", $oPrinter.Name ==>" & $oPrinter.Name & "<==") Next LogMsg("+++: Found " & $cnt & " printers") EndIf EndFunc ;==>test Func doQuery($sQuery, $lnum = @ScriptLineNumber) #forceref $lnum LogMsg("+++:" & $lnum & ": doQuery(" & '"' & $sQuery & '"' & ") entered") Local $oWMIService, $oResults, $errstr Local $wbemFlags = BitOR(0x20, 0x10) ; $wbemFlagReturnImmediately and wbemFlagForwardOnly $oWMIService = ObjGet("winmgmts:\\" & "localhost" & "\root\CIMV2") If (IsObj($oWMIService)) Then $oResults = $oWMIService.ExecQuery($sQuery, "WQL", $wbemFlags) If (IsObj($oResults)) Then LogMsg("+++: doQuery() returns @error = 0, Good: returning the object") Return (SetError(0, 0, $oResults)) ;;; Good: return the object Else $errstr = "" _ & "WMI Query failed." & @CRLF _ & "This is the query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") LogMsg("+++: doQuery() returns @error = 1") Return (SetError(1, 0, $errstr)) ; Error: Query faled EndIf Else $errstr = "" _ & "WMI Output" & @CRLF _ & "No WMI Objects Found for class: " & @CRLF _ & "Win32_PrinterDriver" & @CRLF _ & "using this query:" & @CRLF _ & " " & $sQuery LogMsg("+++: ====>" & $errstr & "<===") MsgBox(0, "ERROR", $errstr) ; Error: Cannot get $oWMIService object Exit (1) EndIf EndFunc ;==>doQuery Func LogMsg($msg, $lnum = @ScriptLineNumber) ConsoleWrite("+++:" & $lnum & ": " & $msg & @CRLF) EndFunc ;==>LogMsg Parsing the returned $oPrinters object shows 5 printers:
      +++:15: FIRST LOOP +++:18: +++: isObj($oP) = 1 +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Microsoft XPS Document Writer<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Microsoft Office Document Image Writer<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Fax<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Canon MG7100 series Printer WS<== +++:22: +++: isObj($oPrinter): 1, $oPrinter.Name ==>Canon MG6100 series Printer WS<== +++:24: +++: Found 5 printers Parsing it again, shows no printers:
      +++:26: SECOND LOOP +++:29: +++: isObj($oP) = 1 +++:35: +++: Found 0 printers

      I did create these few functions several months ago. I post here, if it can interest someone.
      These functions based on WMI queries allow you to manage printers : add / delete printer, driver, port, or obtain configuration, set default printer ... I let you discover it with the code.

      Here is the list of the available functions :
      And some examples :
      #Include "PrintMgr.au3" ; Remove a printer called "My old Lexmark printer" : _PrintMgr_RemovePrinter("My old Lexmark printer") ; Remove the driver called "Lexmark T640" : _PrintMgr_RemovePrinterDriver("Lexmark T640") ; Remove the TCP/IP printer port called "TCP/IP" _PrintMgr_RemoveTCPIPPrinterPort("MyOLDPrinterPort") ; Add a driver, called "Samsung ML-451x 501x Series", and driver inf file is ".\Samsung5010\sse2m.inf" _PrintMgr_AddPrinterDriver("Samsung ML-451x 501x Series", "Windows NT x86", @scriptDir & "\Samsung5010", @scriptDir & "\Samsung5010\sse2m.inf") ; Add a TCP/IP printer port, called "MyTCPIPPrinterPort", with IPAddress = and Port = 9100 _PrintMgr_AddTCPIPPrinterPort("MyTCPIPPrinterPort", "", 9100) ; Add a printer, give it the name "My Printer", use the driver called "Samsung ML-451x 501x Series" and the port called "MyTCPIPPrinterPort" _PrintMgr_AddPrinter("My Printer", "Samsung ML-451x 501x Series", "MyTCPIPPrinterPort") ; Set the printer called "My Printer" as default printer _PrintMgr_SetDefaultPrinter("My Printer") ; Connect to the shared printer "\\\HPDeskjetColor") _PrintMgr_AddWindowsPrinterConnection("\\\HPDeskjetColor") ; List all installed printers #Include <Array.au3> $aPrinterList = _PrintMgr_EnumPrinter() _ArrayDisplay($aPrinterList) ; List all printers configuration #Include <Array.au3> $aPrinterConfig = _PrintMgr_EnumPrinterConfiguration() _ArrayDisplay($aPrinterConfig) ; List all installed printer drivers #Include <Array.au3> $aDriverList = _EnumPrinterDriver() _ArrayDisplay($aDriverList) ; Retrieve the printer configuration for the printer called "Lexmark T640" #Include <Array.au3> $aPrinterConfig = _PrintMgr_EnumPrinterConfiguration("Lexmark T640") _ArrayDisplay($aPrinterConfig) ; Add a local printer port (for a file output) _AddLocalPrinterPort("c:\temp\output.pcl") ; Remove the local port _RemoveLocalPrinterPort("c:\temp\output.pcl") Download link :  PrintMgr.au3
