explorer.exe monopolizando aleatoriamente minha CPU; alguma visão sobre este log do ProcessMonitor?

Meu computador ocasionalmente deixa de responder terrivelmente. A abertura do Process Explorer revela que o explorer.exe ocupa 100% da CPU. Procurei até encontrar o ID do thread que estava fazendo isso e monitorei esse thread com o Process Monitor. Houve muitas ações que o thread estava tentando. Alguns deles resultaram em “SUCESSO” e outros resultaram em “NÃO ENCONTRADO”. Anexei um arquivo Excel com os logs, mas também anexei uma captura de tela com as ações e contagens correspondentes agrupadas/destacadas.

Alguma ideia do que isso poderia ser? Executei uma verificação AV (Microsoft Security Essentials) e ela diz que estou limpo.

De acordo com a pergunta do SLaks nos comentários, o Process Explorer mostra o thread ocupado como SHLWAPI.dll; aqui está a pilha:

Eu costumava ter esse problema no meu equipamento XP e não conseguia evitar que isso acontecesse - o problema parece uma ocorrência anômala. A única solução que consegui encontrar foi matar o Explorer.exe por meio do Gerenciador de Tarefas e reiniciá-lo.

Basta abrir o gerenciador de tarefas (Ctrl + Alt + Delete), navegar até a guia Processos no Gerenciador de Tarefas, encontrar "Explorer.EXE" na lista "Nome da imagem" e, depois de encontrá-lo, selecione-o e pressione o botão Botão "Finalizar processo" no canto inferior direito da janela. Isso matará o explorador.

Feito isso, volte para a aba “Aplicativos” do Gerenciador de Tarefas, pressione o botão “Nova Tarefa” e, na caixa de diálogo que aparecer, digite “Explorer.EXE”. Isso reiniciará o Explorer e deverá resolver o problema.

O explorer.exe aparentemente não gosta quando há atalhos localizados diretamente em Meu Computador. Tente remover o item target.lnk e veja se o comportamento ainda ocorre.

Outra solução possível é ir ao Painel de Controle > Barra de Tarefas e Menu Iniciar > guia Menu Iniciar > personalizar, rolar cerca de 3/4 para baixo e selecionar “pesquisar sem pastas públicas”.
