On WIN 10 there is an option in Local Group Policy Editor to set up it easily:

1. 
   Search: Local Group Policy Editor (you can launch gpedit.msc)


2. 
   Navigate to: Computer Configuration / Administrative Templates / Windows Components / Windows Update
   


3. 
   Double click on: Enabling Windows Update Power Management to automatically wake up the system to install scheduled updates and set it to "Disabled".

Figure for Local Group Policy Editor setting:

After upgrading to Windows 10, the computer in my bedroom kept waking me up at 3AM. Disabling Wake the computer on the MicrosoftWindowsUpdateOrchestratorReboot scheduled task didn't help. Windows turns the flag back on periodically. Even disabling "Disable wake timers" in Power Options didn't help. The UpdateOrchestrator kept orchestrating midnight alarms.

As a solution I've added a powershell script that removes wake settings every hour.

1. 
   

   To allow running powershell scripts: run powershell as administrator, and run:

   
   
   

   Set-ExecutionPolicy RemoteSigned

   
   


2. 
   

   Create a file called "disable_wakejobs.ps1" that contains one line of code:

   
   
   

   Get-ScheduledTask | ? {$_.Settings.WakeToRun -eq $true -and $_.State -ne "Disabled"} | % {$_.Settings.WakeToRun = $false; Set-ScheduledTask $_}

   
   



3. Open Task Scheduler and create a scheduled task.



4. In the "General" tab, set the user account to "SYSTEM" user (or you'll have to update a saved password every time you change your own password.)


5. In the "Triggers" tab, create a trigger that runs the job daily and repeat every hour.


6. In the "Actions" tab, create an action to "Start a program", with "Program/script" set to "PowerShell.exe", and arguments -Command "c:toolsdisable_wakejobs.ps1" (change the path to where you stored disable_wakejobs.ps1 in step 2.)

The PowerShell commands come from this blog post by Reidar Johansen.

This should solve your problem:

1. Search Task Scheduler
   


2. Navigate to Task Scheduler LibraryMicrosoftWindowsUpdateOrchestratorReboot
   Note: Reboot is just a file, but you need to go inside all those folders


3. Right Click Properties then click Conditions
   


4. Uncheck Wake the computer to run this task
   

I am using Wake On LAN (WOL) feature on my computer so that I can wake up my computer remotely if I need to access it while I am away.. in order for WOL to work is that I have to allow my network card to wake the computer when I send the WOL magic packet.

This is somehow causing my computer to wake up randomly for no apparent reason. To know whether this is causing your computer to wake up randomly, type this command in the command prompt:

powercfg -lastwake

If you see something about your network card (as of mine Realtek PCIe).. then you need to go to your network card properties setting and make sure the Only allow a magic packet to wake the computer check box is checked (mine wasn't):

Then pray to your God...

That appears to be the system maintenance task running. If so, you might try disabling system maintenance.

WIN+R control
search for "maintenance" in the search box, select "Change Automatic Maintenance settings".

Clear the "allow scheduled maintenance to wake up my computer at the scheduled time".

See if that helps remove the issue. It's going to be a lot more reliable than some of the other mechanisms proposed.

Applying Andomar's solution, I also got the error:

• Set-ScheduledTask : The parameter is incorrect. At C:UsersFilipscriptsdisable_wakejobs.ps1:1 char:123 + ... Disabled"} | % {$.Settings.WakeToRun = $false; Set-ScheduledTask $} + ~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : InvalidArgument: (PS_ScheduledTask:Root/Microsoft/...S_ScheduledTask) [Set-ScheduledTask], CimException + FullyQualifiedErrorId : HRESULT 0x80070057,Set-ScheduledTask

In my case this was due to a task which cannot be edited (AUSessionConnect within WindowsUpdate to be precise). So I edit the responsible task directly (Reboot within UpdateOrchestrator). The corresponding disable_wakejobs.ps1 file looks like this (for how to use that file, check out Andomar's answer):

Get-ScheduledTask -TaskName "Reboot" | % {$_.Settings.WakeToRun = $false; Set-ScheduledTask $_}

To test the script manually ensure you run it from an elevated PowerShell instance (Run as Admin).

I ran into problem where UpdateOrchestrator re-enabled itself again. This ofcourse caused my computer to wake up from sleep mode by itself (seriously snap you microsoft for also waking me up in the middle of the night). Found some info on reddit that seems to solve it.

Open powershell:

• run: Get-ScheduledTask | where {$_.settings.waketorun}

Open cmd:

• Run SCHTASKS /Change /TN
  "MicrosoftWindowsUpdateOrchestratorReboot" /DISABLE


• Run icacls "%WINDIR%System32TasksMicrosoftWindowsUpdateOrchestratorReboot" /inheritance:r /deny "Everyone:F" /deny "SYSTEM:F" /deny "Local Service:F" /deny "Administrators:F".

This will prevent the task from being enabled again. This assumes you're running an English version of Windows - translate the user names as necessary or find the SIDs, if required.

Based on my experience, you can configure the auto update policy instead as a workaround:

1. Open Local Group Policy Editor (gpedit.msc)


2. Go to: Computer Configuration / Administrative Templates / Windows Components / Windows Update


3. Modify "Configure Automatic Updates", you can enable it and set it as "2 - Notify for download and notify for install" or "3 - Auto download and notify for install"

This way the system doesn't even have the chance to start installing updates, which results in waking up and rebooting in most cases. In addition, you have the control over when to update.

windows 10 has two things you can diable for wake timers

when you go into advanced power setting I found under wake timers you will see disable wake timers then under that you will see an important wake timer, disable that one too.
