I've had to do the following to get WMI working. Follow these steps exactly: 1> Set the following registry key: Key: 'HKLM\SYSTEM\Setup' Value: 'SystemSetupInProgress' Type: DWORD Data: '0' 2> net stop winmgmt /y 3> net start winmgmt 4> <Execute your WMI script(s) now> 5> Reset 'SystemSetupInProgress' to '1' 6> net stop winmgmt /y 7> net start winmgmt NOTE: I've only queried 'Win32_ComputerSystem' for 'model'. Not sure if all functionality is available.
