Computer wakes from sleep automatically every night

Well, it's a nice suggestion. When I run powercfg/requests, I did get all "None" except

EXECUTION:

[SERVICE] \Device\HarddiskVolume2\Windows\System32\svchost.exe (UsoSvc)

Universal Orchestrator

Orchestrator. Go figure. (For effect, say "Orchestrator" like Seinfeld said "Newman".)

1. Windows Update was introduced with Windows 98 and no version has ever had to wake up my laptop at 2 in the morning!
2. And it's not as if the update service is so heavyweight.
3. Again, why does usoft think they know better than me about when to do updates on my computer? Give me the option to specify when updates should occur!

For the past few months I found my computer awake in the morning even though I had put it to sleep when finished working on it the previous day. Running Powercfg /lastwake revealed Update Orchestrator as the task that woke the computer. However that is not a problem!

While the many solutions presented in this forum and across the internet focus on preventing Orchestrator from waking the computer, I don't see that as a problem that needs fixing.

Orchestrator and other tasks such as backups need to run periodically. Doing so at night is preferred so as not to interfere with daytime work. The Orchestrator task on my system was showing a last run time of 11:41 PM each day. I also have a backup that runs at 2:00 AM once per week. My assumption was that both of these tasks would wake the computer, do their job and then the computer would go back to sleep per the power settings. This was clearly not happening in recent months.

The real problem is the computer was not going back to sleep after the wake event.

Powercfg /lastwake only tells us what last woke the computer. It does not tell us what prevented it from sleep.  To determine that...

  Launch a command prompt with admin privileges.

  Run powercfg /requests

You'll see 6 categories. You want to have None under each. If you see an application listed, you may need to take some action in the app's settings or simply uninstall if it is not needed. 

In my case, MiniTool ShadowMaker was listed. I had previously installed that to try it out, but had no need to continue using it. I uninstalled it and ran powercfg /requeststo verify there are now no applications listed.

Since doing that, my computer is always in sleep mode when I check it in the morning. It still wakes up at night as it should for maintenance tasks and backups and then goes to sleep per the Power Plan. Which is what I want it to do.

I just moved to Windows 10 after spending 7 years happily on Win7.  My new machine has Version 1909 and, while it will go to sleep fine, is always awake in the morning.  Asking powercfg what happened points to UpdateOrchestrator:

Wake Source [0]

    Type: Wake Timer

    Owner: [SERVICE] \Device\HarddiskVolume4\

Owner Supplied Reason: Windows will execute 'NT TASK\Microsoft\Windows\

Universal Orchestrator Start' scheduled task that requested waking the computer.

The machine is "up" in the morning and, oddly, leaves the monitor on with no screensaver enabled.  I don't really mind the wake event, but Universal Orchestrator Update seems to be leaving the machine in an unusual state -- incapable of idling.

This misadventure, although slight for me since the desktop is always plugged in, and the lack of end user control afforded in the service scheduling for Universal Orchestra seems to be an unfortunately excellent example of the lack of control that kept me on Windows 7 for so long!

Yeah, from what I can tell UpdateOrchestratorStart is a "one-time only" task created on-the-fly.

I've done two things recently and my machine hasn't woken up in the past two weeks. (Note though that my laptop had been quiescent in this regard for 2-3 months then this UpdateOrchestratorStart task started running at 2 in the morning):

1. A previous poster said to make sure you've turned off all wake timers. I had left mine at "Important wake timers only" but now I've set it to "Disabled": Control Panel - Power Options - Change Plan Settings next to your selected option - Change advanced power settings - Allow wake timers - Disable both On battery and Plugged in.
2. I changed the "active hours" of my computer to the middle of the night so that if Windows decides to update my machine, it's doing it during the day when my machine is already on: Start button - Settings button - Update & Security - Windows Update - Change active hours. I set mine from 5 pm to 9 am.

Obvs. it would be so easy for usoft to allow me to set the time it checks for updates, but somehow, someone in Seattle decided they know it's best to check for updates at gawdawful hours and have no problem waking up my laptop to do so... for a 1 meg update to the antivirus definitions.
