Disable / Remove Windows 10 Sleep Study

Please tell me how I can Disable / Remove Windows 10 Sleep Study

Windows 10 incorrectly identifies my desktop as a tablet, most likely because I am using a Dell touch screen monitor. I want to disable and remove the «Sleep Study» and all components as it is an unnecessary drain on system resources. Please note, this is a DESKTOP system with no battery, no need to monitor screen on times or sleep times. I have tried everything I can find including stopping «ScreenOnPowerStudyTraceSession» in Performance Monitor and setting output files to Read Only. Nothing works. Please help.

As suggested, I reviewed settings at:

Control Panel -> Power Options -> Change Plan Settings -> Change Advanced Power Settings -> Sleep

SETTINGS BEFORE:
Sleep after: Never
Allow hybrid sleep: On
Hibernate after: Never
Allow wake timers: Enable

SETTINGS CHANGED TO:
Sleep after: Never
Allow hybrid sleep: Off
Hibernate after: Never
Allow wake timers: Disable

Then I deleted these files:
Windows\System32\SleepStudy\UserNotPresentSession.etl
Windows\System32\SleepStudy\ScreenOn\ScreenOnPowerStudyTraceSession-####-##-##-##-##-##.etl
(About 20 files here in the last two days)

And then rebooted.

Since then I have had five new .etl files appear. Apparently the fix we tried didn’t work. (But obviously thank you very much for giving me something to try!) Any other suggestions?

PS — I did recheck all settings; they held / did not revert back to previous values.

Should probably mention that even a Desktop System usually has a battery.

It helps your clock keep the correct time. 😉

Your suggestions have absolutely noting to do with the original question.

There is no reason for this «SleepStudy» to be creating an endless list of .etl files on my computer. I want to remove it completely from MY computer. Let me say that again: it’s MY computer. I should have complete freedom to remove anything from it that I don’t want on it! If doing so bricks my PC, so be it. That’s MY problem since it’s MY PC!

The takeown and ICACLS commands get me ownership of the folders but access to the ScreenOnPowerStudyTraceSession file is still denied. The takeown and ICACLS don’t work.

How do I unlock the SleepStudy folder and files so they can be deleted permanently?

Yes, if you are able to take full control of the folders, you can completely delete the Sleep Study folder from the System 32 folder. I have done so many, many times. But that is of no real importance, because the Sleep Study folders and a new batch of *.etl files will reappear overnight.

The Sleep Study process is smart enough to create the necessary folders if they do not exist, and promptly begins filling them with more files. I would still like to find a permanent fix for this issue but to be honest, I have not spent a lot of time on it lately. I’ve thought about adding a simple batch file to my start up that will delete the files, but that would make it difficult to know if the files were still being produced. It would remove the incentive to find a way to terminate and remove the process that is creating the mess.

I will look at it again as time permits, but if anyone actually KNOWS how to curtail the Sleep Study process, don’t be shy about sharing your success. 🙂

Having taken ownership of the 2 folders, I tried something I saw in another post.

«I found a solution for this problem, by setting «UserNotPresentSession.etl» to Read-only.

1. Go to: «C:\Windows\System32\SleepStudy».
2. Click the right mouse button on file: «UserNotPresentSession.etl» and then «Properties» from the list.
3. Check «Read-only» checkbox and save changes.
4. IMPORTANT: Restart your computer.«

This didn’t work when I tried it b4 taking ownership of the folders. When I tried to set the files to read only I got one of the usual you can’t do that messages. However, having taken ownership of the folders, for some reason, when I set the files to Read-only it stuck.

When applying Read-only status I did NOT click the Apply button, just OK. I restarted my computer with the explorer window still open. Don’t really know if that matters. Now both files are maintaining the Read-only status and it seems no more ScreenOnPowerStudyTraceSession.etl files are being written. This may prove to be wishful thinking as I’m actually expecting the files to reappear at some point. Just a hunch. I’ll confirm one way or the other in a little while.

Black screen after Sleep mode in Windows10

When my computer goes into sleep mode it is impossible to wake it up again without holding down the start key for 10 seconds, then turning back on again. This sleep (coma might be a better word for it?) happens either due to inactivity or if I close the lid. I have changed the inactivity setting to never to stop that one from happening.

There is another question on this forum that is pretty much the same, but the answer from Microsoft has not understood the problem, so the advise is not appropriate (http://answers.microsoft.com/en-us/windows/forum/windows_10-other_settings/screen-will-not-turn-back-on-or-remains-black/b94c23a1-99bd-46db-b16d-535aaa641b5a).

In my research for a fix to this problem I have encountered a number of problems with people using the Windows 10 Technical preview, with people upgrading to Windows 8 and with people upgrading to Windows 8.1. This seems to be a recurring problem and one that should really be fixed before any type of release. (Einstein’s definition of insanity: doing the same thing over and over again and expecting different results.)

I am trying to work out why I forgot my one cardinal rule when it comes to computing: Never install a Windows upgrade until all the bugs have been fixed. I have read that I can revert back to Windows 8.1, but do not trust Windows to try that.

I have an HP Pavillion 15 Notebook PC.

I have an HP pavilion 17 notebook with the same problem.

The power to the laptop does not shut down when I shut down Windows, I have to manually turn off the power.

I also changed the settings to «never» on both sleep and screen (click on settings, click on system, click on power/sleep, scroll to «never» on both) since Windows was shutting down but leaving the power on. At least for now, when I shut Windows down I can manually turn off the laptop a few seconds later. This laptop is almost always plugged in so I don’t worry about the battery.

This is like my husband turning off the TV but leaving the lights on!—- not a good thing.

Thanks Susan, your reply has helped me to find a temporary solution. I hadn’t tried shutting my computer down since first experiencing this problem so did not know it is a power issue rather than a screen issue. Whether shutting down or putting it to sleep mode, the process does not complete. The computer remains on until the battery is depleted.

I have found this website: (Removed) which says that for Windows 8, 8.1 and 10 Microsoft introduced a new (and default) method of shutdown called Hybrid Shutdown. This ‘ decreases the shutdown time by hibernating the kernel session, instead of completely closing it. When the PC is powered on again, the kernel session is revoked from the hibernation, so it decreases the booting time as well. ‘ However, there are still errors in this Hybrid Shutdown feature which means that for many computers the shut down process is not completed and the computer just freezes or hangs.

A solution is to disable the Hybrid Shutdown by following these steps:

1. Go to Search, type power options and click on Power Options from search results
2. On the left side of the window click on Choose what the power button does
3. If needed, click on Change settings that are currently unavailable, under Define power buttons and turn on password protection
4. From the enabled options under Shutdown settings section, uncheck Turn on fast startup (recommended) checkbox to disable Hybrid Shutdown.
5. Click Save changes button to save the modified settings.
6. Close Power Options window when done.

This will not affect the faulty sleep function but will enable us all to turn off our computers when desired.

How to sleep the screen on Windows 10

Sep 23, 2019

If you leave your system unattended, your screen will eventually go to sleep. If you don’t return to it, the system will lock itself once the set amount of time has expired. If you want to turn the display off at will, you can set up the power button to do so. The power button may not be the most convenient way to go about it, especially if it’s hard to reach. Instead of a hard button, you can add a simple soft button and keyboard shortcut that will sleep the screen. Here’s how you can get it.

Sleep screen on Windows 10

In order to sleep the screen with a soft button or a keyboard shortcut, you have to install a free, open-source app called ScreenSleep. Download it from Github and run it.

The app runs in the system tray and adds a display/monitor icon to it. If you click it, a menu will open with an option to sleep the screen. Since this take two clicks, the quicker way to use the app is with its keyboard shortcut.

The default keyboard shortcut is Ctrl+Shift+M but, you can change it. Click the app’s icon in the system tray, and select Settings from the menu. The settings window only has one item that you can change i.e., the keyboard shortcut. Click inside the box where the shortcut is, and type the new one you want to use.

ScreenSleep can be set to run at startup from the app’s own built-in settings.

The app works great with a single monitor, and with multiple monitors. It can sleep both an external and an internal display without any problems. The sleep applies only to the displays. It has nothing to do with the Sleep option for Windows 10. It’s an entirely different feature.

The Windows 10 power options let you set when the display is put to sleep. You can change when the system puts the display to sleep and it works perfectly but it’s time bound. You have to wait for a certain time, even if it’s just a minute, to expire in order for the display to go to sleep. This app gives you a method to sleep it at will.

Since this is just putting the display to sleep, it’s not a security layer of any sort. The app isn’t too old and it appears to be under active development. Maybe it will eventually allow users to selectively sleep a display.
