TimE TimE Fresh Scripter Registered: 2009-08-17 Posts: 5 Loc: Jacksonville, FL	I need to make sure "wuauserv" is enabled on all my Windows machines. I have a GPO for WSUS but I noticed that if the Startup Type is set to "Disable" GPO will not work. How do I (1) change the startup type to "Automatic" and (2) once changed to Automatic start the service. Any guidance will be greatly appreciated.

The latest copy of WMISvcMgr can be obtained from the UDF Library in the Resources section of my web site. You'll also find a complete library of WSUS functions there along with a sample script to control the download and installation of updates via WSUS. The script integrates with a scheduled task to repeatedly download and install updates during a defined change window until all updates are applied. Without this, WSUS only installs the dependent changes and waits until the next change period to continue installing. Glenn _________________________ Actually I am a Rocket Scientist! $\:D$

As Glenn pointed out, there are several already completed UDFs readily available for handling services. But here is a small example that I just wrote up that accomplishes what you specifically asked for. You can play around with it, and look at Glenn's suggestions for more advanced options.

Code:

$ServiceStatus = IsServiceRunning("wuauserv")

If $ServiceStatus[0] = "Running"
   ? "Automatic Updates is Running"
   If InStr($ServiceStatus[1],"Auto")
      ? "Automatic Updates is set to Auto"
   Else
      If ChangeServiceState("wuauserv","Automatic")=0
         ? "Automatic Updates Has Been Set to AUTO"
      Else
         ? "Error Setting Automatic Updates to AUTO"
      Endif
   EndIf
Else
   If ChangeServiceRunState("wuauserv","Start")=0
      ? "Automatic Updates Has Been Started"
      If ChangeServiceState("wuauserv","Automatic")=0
         ? "Automatic Updates Has Been Set to AUTO"
      Else
         ? "Error Setting Automatic Updates to AUTO"
      EndIf
   Else
      ? "Error Starting Automatic Updates, Still not Running"
   EndIf
EndIf

get $

Function IsServiceRunning($svc)
; Returns a 2 element array with the Running status[0] and the start mode [1]
   $objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\"+@WkSta+"\root\cimv2")
   $colListOfServices = $objWMIService.ExecQuery("Select * from Win32_Service WHERE Name='$svc'")
   For Each $objService in $colListOfServices
      $IsServiceRunning = $objService.State,$objService.StartMode
   Next
EndFunction

Function ChangeServiceState($svc,$state)
;Call function with either 'Automatic','Manual', or 'Disabled'
   $objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\"+@WkSta+"\root\cimv2")
   $colListOfServices = $objWMIService.ExecQuery("Select * from Win32_Service WHERE Name='$svc'")
   For Each $objService in $colListOfServices
      $ChangeServiceState = $objService.ChangeStartMode($state)
   Next
EndFunction

Function ChangeServiceRunState($svc,$runstate)
;Call function with either 'Start' or 'Stop'
   $objWMIService = GetObject("winmgmts:{impersonationLevel=impersonate}!\\"+@WkSta+"\root\cimv2")
   $colListOfServices = $objWMIService.ExecQuery("Select * from Win32_Service WHERE Name='$svc'")
   For Each $objService in $colListOfServices
      If $runstate="Start"
         $ChangeServiceRunState = $objService.StartService()
      Else
         If $runstate="Stop"
            $ChangeServiceRunState = $objService.StopService()
         Else
           Exit 87
         EndIf
      EndIf
   Next
EndFunction

Tesdall Tesdall Getting the hang of it Registered: 2009-10-02 Posts: 78 Loc: USA	you could do something like this: Code: Break on Writevalue('HKLM\system\currentcontrolset\services\wuauserv', 'Start', "2", "REG_DWORD") net start "wuauserv" Exit Something like that anyway. for reference: Code: Boot 0x0 System 0x1 Automatic 0X2 Manual 0x3 Disabled 0x4 /Quick and Dirty Update: Or you can just do what Citrixman says $\:\)$ Edited by Tesdall (2011-02-14 09:41 PM) Edit Reason: Being quick and Dirty _________________________ Where ever you go, there you are.
