Ferramenta de avaliação do sistema Windows parou de funcionar

Question

Eu tenho o windows 7 sp1 com todas as atualizações mais recentes.

Quando tento atualizar o "Windows Experience Index", recebo um erro: "Ferramenta de avaliação do sistema do Windows parou de funcionar" A falha está no arquivo winsat.exe. Eu tento várias soluções encontradas na web, como:

1) No prompt de comando, execute o "WinSAT formal" 2) Exclua os arquivos .xml de C: \ Windows \ Performance \ WinSAT \ DataStore e tente novamente executar o WEI.

Ainda estou recebendo o erro acima e o WEI não conclui o processo.

O WinSAT.log contém estes:
