I have several Servers where the Service for an application was mis-configured to Log On (Log On As) a Domain\Account.

I need to set these Services on each Server back the the Default Setting Log On (Log On As) Local System Account.

I have found the example of finding the order for the WMI change i.e.-

PS C:\\> $svc = get-wmiobject win32\_service -filter "name='Service\_Name'"

PS C:\\> $svc.GetMethodParameters("change")

But I cannot find an example to set the StartName back to the Default Setting.

Would this all be a $null ??

Example per Jeff Hicks - [https://4sysops.com/archives/managing-services-the-powershell-way-part-8-service-accounts/](https://4sysops.com/archives/managing-services-the-powershell-way-part-8-service-accounts/)

PS C:\\> $svc | Invoke-WmiMethod -Name Change -ArgumentList @($null,$null,$null,$null,$null,$null,$null,$null,$null,$null,$null)

Or would the correct way to be using LocalSystem?

PS C:\\> $svc | Invoke-WmiMethod -Name Change -ArgumentList @($null,$null,$null,$null,$null,$null,$null,$null,$null,"LocalSystem",$null)

I know this can easily be done with the CIM as this example from Jeff Hicks

PS C:\\> Get-CimInstance win32\_service -filter "name='yammmsvc'" | Invoke-CimMethod -Name Change -Arguments @{StartName=".\Jeff";StartPassword="P@ssw0rd"}

But I do not know what to use for StartName...

I believe I found it. I would like verification if this is not the correct way…

I was running this with an Admin Logon Credential and was getting a return code of 2, however once I ran the PowerShell session As Admin this worked.

PS C:&gt; Get-CimInstance win32\_service -filter “name=‘some\_service\_name’” | Invoke-CimMethod -Name Change -Arguments @{StartName=“LocalSystem”}

Yes, this is the correct method. If you wanted to add a password, add `StartPassword` to the hash table. `StartPassword` accepts a string value, just be careful when configuring.
