Newer versions of Windows 10 will not idle, screensaver or go to sleep

I am using Windows 10 Professional version 1803. If I update to the latest version, something about that prevents my computer from idling. As such, my screensaver and power options do not automatically activate. I have to use them manually and they only work when I do set them manually. Right now it's working as expected but I can't update unless it will give me the ability to turn off the monitor, etc.

Any ideas?

Well my PC won't go to sleep, either.

Hello Ketchupp and welcome to TF ,

Verify your BIOS and drivers are up to date according to the PC manufacturer.

Please run the following from an admin powershell "powercfg /requests" , then close any browsers and stop any audio/video from playing and run it again and either paste the output withing php tags or a screenshot for both cases.

If you try to sleep the PC via CTRL-ALT-DEL power icon in bottom right, select sleep, does it sleep then?

Have you checked your power plan options to make sure PC and display are set to sleep after a period?

Please update your PC details using https://www.tenforums.com/profile.php?do=extra ..... currently just has "OS: Windows 10 Pro 1803"

Can confirm, after updating to 844 automatic sleep mode not happening. Set at 30 minutes and was working perfectly before.
Using CTRL-ALT-DEL power icon in bottom right does work.

From admin powershell "powercfg /requests" - post the output.

@ugatme,
MoUsoCoreWorker is related to Windows Updates - some crap M$ recently started doing caused my PCs to do this too and stop sleeping. My simple fix is to go into Windows Updates and pause updates for 35 days.

I will unpause it on the 2nd Tuesday of the month after I make a full Macrium Reflect backup of my PC, then let Windows install the monthly Cumulative Updates of the month, then pause again for 35 days. With WU paused, the PC still gets security/AV updates - and sleep works . I just recently discovered that pausing updates will fix the non-sleep problem.

Give it a try or ask questions if you have them

You can set your PC to sleep after a few minutes to test this quickly.

If you have a browser open playing YouTube videos for example, that will also prevent the PC from going to sleep, which is why I had you run the command twice. After you pause WU (and you're not playing any videos or music), you should see all the outputs of powercfg /requests say None - that means the PC should sleep.
