Is there a way to refresh WMI without restarting Windows?

Be it either with WMIC, Powershell or directly interacting with WMI itself.

The situation is that Windows reads from DMI during boot and this is the information you can find in the hardware based WMI classes such as Win32_Baseboard. The problem I run into is that if I change the data in the DMI, Windows does not return the new information when reading from the WMI class again. It seems to be because it had populated that information on boot, it doesn't expect it to change.

I have verified the information is changed in the firmware, but the relative fields in WMI do not update automatically.

I presume you've already tried restarting Windows Management Instrumentation service? That's the only thing I can think of.
