Hi,

this script repairs and recreates the WMI Repository of a Windows. For example, this occurs sometimes if you clone a Windows machine with an installed SCCM/SMS Client. The typical error in this case is “Failed to open to WMI namespace ‘\\.\root\CCM\SoftwareUpdates\DeploymentAgent’ (8007045b)”

Lasts start. Start a Powershell console as Administrator. Stop all services. Sometimes other services depends on the WMI Service and does not accept a stop request. Therefore you cannot stop the WMI service. TrendMicro Office is such a service. You have to kill them by TaskManager.

# Stop WMI
# Only if SCCM/SMS Client is installed. Stop ccmexec.
Stop-Service -Force ccmexec -ErrorAction SilentlyContinue
Stop-Service -Force winmgmt

(Re)Register WMI binary components

[String[]]$aWMIBinaries=@("unsecapp.exe","wmiadap.exe","wmiapsrv.exe","wmiprvse.exe","scrcons.exe")
foreach ($sWMIPath in @(($ENV:SystemRoot+"\System32\wbem"),($ENV:SystemRoot+"\SysWOW64\wbem"))){
	if(Test-Path -Path $sWMIPath){
		push-Location $sWMIPath
		foreach($sBin in $aWMIBinaries){
			if(Test-Path -Path $sBin){
				$oCurrentBin=Get-Item -Path  $sBin
				Write-Host " Register $sBin"
				& $oCurrentBin.FullName /RegServer
			}
			else{
				# Warning only for System32
				if($sWMIPath -eq $ENV:SystemRoot+"\System32\wbem"){
					Write-Warning "File $sBin not found!"
				}
			}
		}
		Pop-Location
	}
}

Reregister WMI Managed Objects

if([System.Environment]::OSVersion.Version.Major -eq 5) 
{
   foreach ($sWMIPath in @(($ENV:SystemRoot+"\System32\wbem"),($ENV:SystemRoot+"\SysWOW64\wbem"))){
   		if(Test-Path -Path $sWMIPath){
			push-Location $sWMIPath
			Write-Host " Register WMI Managed Objects"
			$aWMIManagedObjects=Get-ChildItem * -Include @("*.mof","*.mfl")
			foreach($sWMIObject in $aWMIManagedObjects){
				$oWMIObject=Get-Item -Path  $sWMIObject
				& mofcomp $oWMIObject.FullName				
			}
			Pop-Location
		}
   }
   if([System.Environment]::OSVersion.Version.Minor -eq 1)
   {
   		& rundll32 wbemupgd,UpgradeRepository
   }
   else{
   		& rundll32 wbemupgd,RepairWMISetup
   }
}
else{
	# Other Windows Vista, Server 2008 or greater
	Write-Host " Reset Repository"
	& ($ENV:SystemRoot+"\system32\wbem\winmgmt.exe") /resetrepository
	& ($ENV:SystemRoot+"\system32\wbem\winmgmt.exe") /salvagerepository
}

Starting services

Start-Service -Force winmgmt
Start-Service -Force ccmexec -ErrorAction SilentlyContinue
