Existem algumas coisas que você pode tentar.
1) Se disponível (ou seja, versões que não sejam da Home), você pode usar as Políticas de Grupo locais para desabilitar o Windows Update contra o computador:
- Iniciar
gpedit.msc
- Navegue até
Computer Configuration -> Administrative Templates -> Windows Components -> Windows Update
- Modifique a diretiva "Ativando o gerenciamento de energia do Windows Update para ativar automaticamente o sistema para instalar atualizações agendadas".
Specifies whether the Windows Update will use the Windows Power
Management features to automatically wake up the system from
hibernation, if there are updates scheduled for installation.
Windows Update will only automatically wake up the system if Windows
Update is configured to install updates automatically. If the system
is in hibernation when the scheduled install time occurs and there are
updates to be applied, then Windows Update will use the Windows Power
management features to automatically wake the system up to install the
updates.
2) Desative os cronômetros do Wake para o plano de energia atual (isso deve desabilitar os cronômetros de ativação do todo software):
- A program or scheduled task might be waking your computer. By default, Power Option settings do not allow scheduled tasks to wake
the computer from sleep or hibernate. However, some programs might
awaken the computer if these settings have been changed.
To prevent programs from waking your computer
Open Power Options by clicking the Start button , clicking Control Panel, clicking System and Security, and then clicking Power Options.
On the Select a power plan page, click Change plan settings for the plan that you want to change.
On the Change settings for the plan page, click Change advanced power settings.
On the Advanced settings tab, expand Sleep, expand Allow wake timers, choose Disable for both when your computer is running on
battery and when it's plugged in, and then click OK.
