AVISO: faltam registros do WMI ProgID

Iniciei uma das minhas máquinas virtuais do Windows Server 2012 R2 hoje e recebi o seguinte aviso:

AVISO: faltam registros do WMI ProgID

A princípio só vi um erro vago no gerenciador do servidor:

Depois de executar o WMI Diagnosis Utility, obtive mais informações do arquivo de log onde encontrei o aviso:

O que eu fiz até agora:

• Comando sugerido executado no arquivo de log:REGSVR32.EXE C:\WINDOWS\SYSTEM32\WBEM\WBEMDISP.DLL
• Tentei recuperar todos os arquivos .mof (talvez eles estivessem corrompidos). Não consegui fazer os comandos sugeridos funcionarem.
• Registrando novamente minhas DLLs na pasta do Windows:Dir *.dll /s /b > c:re-regdll.bat
• Usei um aplicativo de reparo do Windows do tweaking.com para reparar o WMI.
