How to remove published wmi schema?

Question

I've published schema, and no longer have the dll's that contained the wmi provider that the schema was published from. How can I remove the schema?

Answer 1

If you are talking about the assembly from your other question, you can simply use wbemtest.exe:

• Connect to Root namespace
• Enum instances... button (Superclass name: __Namespace)
• Delete instance named Test or MyTest

That will delete the entire namespace including all the classes you created. If you want to delete a class and leave the namespace

• Connect to Root\Test
• Enum classes... button (Recursive)
• Delete the classes you want

If there are multiple machines this can be automated using WMI scripting library or System.Management. With MOF you can use #pragma deleteclass. If the schema was created with #pragma autorecover you need to remove the entry from

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WBEM\CIMOM\autorecover mofs
