O que significa SHUTDOWN_REASON_AUTOSTOP ao atualizar para o Windows 10?

Question

Estou tentando atualizar o Windows 7 do Dell Laptitude E6430 para o Win 10. Mas ele ficou com 85% de atualização com configuração de 42% por 12 horas sem nenhuma atividade no disco rígido. Depois de desligá-lo e deixá-lo reverter para o Win 7, eu olhei setuperr.log, setupact.log, setup.etl. De acordo com setuperr.log, parece que o instalador teve um problema com o arquivo appdb.dat. Mas com base no setupact.log, o instalador continuou 2-3 minutos depois disso, de repente parou com razão SHUTDOWN_REASON_AUTOSTOP ao mover arquivos de documento. E eu nem entendo o que setup.etl diz.

A seguir estão suas últimas entradas. Qualquer pista para resolver este problema será apreciada.
