How to Enable or Disable to Allow Wake Timers in Windows 10
A wake timer is a timed event that wakes the PC from sleep and hibernate states at a specific time. For example, a task in Task Scheduler set with the "Wake the computer to run this task" check box checked.
Important wake timers are a new class of wake timer in Windows 10 that includes things like reboots after a Windows update that requires one. They supersede all other settings.
