In this example, the scheduled task “Universal Orchestrator Start” woke the computer up from sleep.

Scroll down to the bottom and find the last hibernate stat. Read in the “EXIT REASON” column, the reason why your system woke up.

In the above example, the reason was:

Timer – will execute “NT TASK\Microsoft\Windows\UpdateOrchestrator\Universal Orchestrator Start” scheduled task that requested waking the computer.

It’s obvious the scheduled task Universal Orchestrator Start is what woke the computer up.

To disable the “Universal Orchestrator Start” task;

  1. Open Task scheduler as Administrator;
Run Task Scheduler as administrator

2. In the Task scheduler console select; Task Scheduler Library > Microsoft > Windows > UpdateOrchestrator

The Universal Orchestrator Start Task Wakes the computer when running.

Under the UpdateOrchestrator folder, select the”Universal Orchestrator Start” task, then click on the “Conditions” panel.

You need to uncheck the “Wake the computer to run this task” checkbox.

But if you do that you’are going to get an error message like this one:

Task Scheduler: An error has occurred for task Universal Orchestrator Start. Error message: The following error was reported: The supplied variant structure contains invalid data.

This error is generated because this task runs under System account privileges that are higher than the Administrator privileges.

So unless you run the task scheduler with the system account, you can’t disable this option.

PsExec.exe -si cmd.exe
Run PsExec.exe -si cmd.exe
  • In the new command prompt window, type the “whoami” command, to ensure you are running it with the System account privileges:
whoami command
whoami command

one you ensure that you running the command prompt as the Local System user, then type “taskschd.msc” to open task scheduler and uncheck the “Wake the computer to run this task” checkbox.

2. Use Nsudo Tool

If you are not comfortable typing commands, then you can use NSudo, a graphic tool that allows you running programs with System account privileges.

  • Download NSudo;
  • Extract the content of the ZIP file to a location of your choice;
  • Go to the following folder: \NSudo Launcher
  • Right-click on NSudo.bat and choose Run as administrator
  • In the user list, select “System“;
