CIM, Win32_OperatingSystem, and Win32ShutdownTracker - powershell

Question

I’m trying to convert some PowerShell code from using WMI to using CIM. I had a function which used Win32ShutdownTracker (https://msdn.microsoft.com/en-us/windows/desktop/aa394057) to reboot a system, with a timeout, comment, and reason for initiating the reboot. Using WMI I had to give the account running the reboot permissions using “psbase.Scope.Options.EnablePrivileges = $true” even though the account was already an administrator on the local system. I have not figured out how to give the same permissions using CIM and it seems without them, I’m unable to reboot the system. Also, the class binding does not seem to work. Any help would be greatly appreciated.
I've tried many combinations of CIM, including getting the object then invoking it and calling the class directly and none have worked.
WMI Code (Works without issue):
$OSObject = Get-WmiObject -Class Win32_OperatingSystem
$OSObject.psbase.Scope.Options.EnablePrivileges = $true
$OSObject.Win32ShutdownTracker(300,"This is a test",2147745794,6)
CIM Code I've tried (Does not work):
$OSObject = Get-CimInstance -Class Win32_OperatingSystem
$OSObject.psbase.Scope.Options.EnablePrivileges = $true
The property 'EnablePrivileges' cannot be found on this object. Verify that the property exists and can be set.

Answer 1

This works for me:
$arguments = #{
Timeout = [System.UInt32]300
Comment = 'This is a test'
ReasonCode = [System.UInt32]2147745794
Flags = 6
}
Invoke-CimMethod -Query 'SELECT * FROM Win32_OperatingSystem' -MethodName 'Win32ShutdownTracker' –Arguments $arguments
