Computer wakes from sleep automatically every night

It is very strange that Microsoft has said nothing about this. Enough people have this issue which was posted 8 months ago. My computer never used to behave like this. I disabled the task.

It would be nice to get an official fix.

I think i found a fix that doesn't require downloading anything or complicated steps. 

It's worked for me so far.

1.  Go to: Control Panel\Hardware and Sound\Power Options\Edit Plan Settings (it may also be called Change plan settings)

     (you can alternatively just search for "Edit power plan" in the windows search bar)

2. Click "change advanced power settings"

3. Go to "Sleep->Allow wake timers" and change the setting to Disable.

If this doesn't work, then using psexec like RichStevens2 suggested might be the way to go.

The directions i found on another forum was helpful:

"1. First go here to download PsTools. Extract it to a folder on your desktop. 

2. Open Start and type cmd. Right-click the program and choose to run as administrator.
3. Navigate to the folder where you extracted the tools by typing "cd C:\Users\Username\Desktop\Pstools", replace Username with your username and Pstools with the folder where you extracted the tools.
4. When you have navigated to the correct folder, copy the following command without the quotes: "psexec.exe -i -s %windir%\system32\mmc.exe /s taskschd.msc".
5. Open the command window and right click, choose paste. Press enter.
6. Navigate to Task Scheduler Library -> Microsoft -> Windows -> UpdateOrchestrator.
7. Right click the task called Reboot and click on Disable.
8. The task should now be disabled"

Hopefully one of these two options works for ya'll

If this doesn't fix it, try the same steps, but disable "Universal Orchestrator Start" instead. That was the one that was waking up my computer.

These have all been posted several times over the last year. The only one that works (doesn't get reset by Windows) is the first one  - disabling "wake from sleep". That is not a fix but a work-around.

Microsoft has not yet noticed the user frustration posted here with badly written updateorchestrator software that wakes computers and leaves them powered ON.

I think I didn't see this workaround posted already, so here goes...

Power and sleep settings, then Additional power settings, Change plan, Change advanced settings:

Select Sleep>Allow wake timers>Disable.

For a week now the computer stays asleep both on standby and in hybernation.

Only works for you if you think you don't need wakeup timers - which I don't.

Prior to this I tried removing all things from startup, also tried disabling "Allow scheduled maintenance to wake up at the scheduled time" but that didn't work.

I did this a week or so ago and so far it's stayed in Sleep mode overnight

Everyone who hasn't tried this, give it a shot, much easier than the wonky scheduled task manipulation

Here's the problem with that "solution". If you run ANYTHING else yourself: virus scans, computer backups, anything else that wakes the computer automatically, ALL of those things will cease to function properly. This solution only works if you don't do anything at all that needs to wake the computer.
