Is it possible to provide a value in MOF file to overwrite that from CIMWin32 provider?

Question

Dear experts,

I want to overwrite a value in Win32BIOS . By default it is not possible , then I create/compile mine MOF file to generate a new Win32_BIOS class to provide the value in instance . The flaw is I can't fill other fields with real value.

Is it possible to derive from CIM_BIOSElement and fill values from CIMWin32 , but the specific field is overwrite with my value ?

Thanks

Hello there,

Yes it is possile to provide values to MOF files.

MOF files are usually automatically compiled during the installation of the systems with which they are provided, but you can also compile MOF files by using this tool.

https://learn.microsoft.com/en-us/windows/win32/wmisdk/mofcomp

It may not collect dynamic registry values using MOF, the MOF code is edited by SCCM, if we change the code that has been written, it maybe cause confusion. If the values are static, we could run some query to achieve it.

Hope this resolves your Query !!

I've created my MOF file and compiled , but don't know how to overwrite the value from CIMWin32.
My experimental Mof file is like below , compilation succeed although Version value still inherits from CIMWin32 , other than my 999 :

Managed Object FormatCopy

#pragma namespace("\\\\.\\Root\\CIMv2")
[Dynamic,Provider("CIMWin32") : ToInstance,Locale(1033) : ToInstance,UUID("{8502C4E1-5FBB-11D2-AAC1-006008C78BC7}") : ToInstance] 
class Win32_BIOS : CIM_BIOSElement
{
[read , write ,key : ToSubclass,Override("Version") : ToSubclass] string Version="999";
}
