Esta é a pilha de chamadas do arquivo de despejo:

como podemos ver, parece que o Windows estava esperando por um dispositivo para "ejetar" (= seguro para remoção) (QueryRemoveAndEject)

e, em seguida, ocorreu um tempo limite ...

Você provavelmente tem um dispositivo plug and play defeituoso no seu computador, tente desconectar tudo (especialmente as unidades USB!)
