Windows 11 Screensaver / Display Sleep functions not working

Me too. This is such a major issue. I cannot believe there is no way to debug this. I have tried all the ideas in this thread. I even tried with windows rollback options. Powering down monitors, and disabling the screensaver worked fine in windows 10. I was going to try a complete Windows reset, but don't have much confidence that would do anything ether and it takes so much time to reinstall everything. Can someone from MS please help with this. Is there a debug mode to see if the daemons are running and what is blocking them from activating the screen saver?

I'm the same. Run everything in the thread. Still no screen saver or monitor sleep. Wasted so much time on this and with electricity prices as they are it is a very bad time for this to happen. I am using dual monitors as well. Please fix!

Ditto and ditto. I give up. So, I tried a couple of Mac OS "hot corners" type apps for Win, and this one works fine with Win 10 and Win 11: WinXCorners — Hot Corners for Windows 10

And, it's free. There's no timer on it, so you have to manually move the mouse to a corner to start the SS. But, since the chances of MS fixing this are nill, it's better than nothing. <- That sounded like a snark against "WinXCorners" but wasn't meant to be: that is a wonderful program and thanks for making it winxcorners people. Okay bye now.

Thank you!!!! :-)

I forgot to power off my PC this weekend before heading out to my cottage. Because of this issue which Microsoft still hasn't fixed, I now have OLED burn in on my $2000 monitor. Neither the screensaver, monitor sleep, or computer sleep functions kicked in (all of which were enabled, and I have tried every solution on this thread) Luckily I have a Dell so it should be covered by warranty but this is unacceptable there is still no response from Microsoft on this.

Yeah, that's partly what got me to post here earlier. I got permanent burn-in on a Wacom Cintiq display. Not covered under warranty, unfortunately. This bug caused permanent damage to my hardware.

I've tried all the fixes prescribed in this thread and appreciate everyone's input. Unfortunately none of the prescriptions worked. Going on months of frustration I reviewed what apps were using my battery (screen saver issue happened both with battery and when plugged in) and noticed Adobe Creative Cloud using a lot of background resources. This app is set to open on startup. Well, I closed the program and unchecked "open at startup" and guess what, it solved the problem. So for those who can't fix the problem look at your programs running in the background.

Hey Miaent, you're a genius! The amount of time I've wasted on this. I stopped Adobe Creative Cloud loading on startup as you suggested and bingo, everything back to working. Thank you for posting this. It is a great relief to have everything back working. So glad you stuck with it! Brilliant!

You are the winner for this thread for me. Creative cloud was the issue for me also. For others, you have to open the creative cloud app, click the lines in the upper left corner, choose file, then preferences. Turn off "launch on start up". Hopefully that works for others. Thanks MIAENT!

Not the problem for me as I am not using this software. Makes me think it could be another software causing the issue however I still had the problem off a clean/fresh install of Windows before installing anything.
