Confuso - por que meu Windows 10 foi reiniciado mesmo que nenhuma atualização tenha sido gravada?

Question

Acabei de testemunhar um comportamento muito estranho na minha máquina Windows 10 Home . Eu tranquei o laptop para ir jantar, e quando voltei e o destranquei, era óbvio que o Windows havia reiniciado. O Excel e o Word abriram com salvamentos de recuperação, outros programas foram fechados, alguns programas que normalmente são inicializados juntos com o sistema estavam em execução, apesar de eu os ter fechado antes.

Eu entrei às 19:00 de 25/02. Eu tranquei o laptop 1-2 horas antes, então o problema deve ter ocorrido naquele tempo. Abaixo algumas infos do Visualizador de Eventos (registros do sistema; também posso postar o log do aplicativo, se necessário):

O mais estranho é que no histórico do Windows Update, nenhuma atualização do sistema foi instalada hoje. Tenho problemas em entender o que aconteceu e gostaria de evitar isso daqui para frente. Alguma idéia do que está errado?

    

Answer 1

Eles parecem suspeitos: Warning 25/02/2018 18:05:34 Kernel-PnP 219 (212) e Error 25/02/2018 18:05:33 hpdskflt 1001 None e este pode dizer por que houve uma reinicialização: Information 25/02/2018 18:05:00 User32 1074 None

Além disso, há definitivamente alguma atividade de atualização do Windows em andamento: Information 25/02/2018 17:41:32 WindowsUpdateClient 19 Windows Update Agent Information 25/02/2018 17:41:32 WindowsUpdateClient 43 Windows Update Agent

Você verificou os detalhes do User32, que diz:

The process c:\windows\system32\svchost.exe (LAPTOP-XX) has initiated the restart of computer LAPTOP-XX on behalf of user NT AUTHORITY\SYSTEM for the following reason: Operating System: Service pack (Planned) Reason Code: 0x80020010 Shut-down Type: restart Comment: The strange thing is still that there is no update listed in the Windows Update history...

Isso indica claramente que uma instalação do Windows Update / feature pack é responsável pela reinicialização. Observe que essas instalações de feature pack nem sempre aparecem na guia de configurações do Windows Update.
