MoUsoCoreWorker.exe Preventing Monitors from turning off
I have a desktop pc that is also my home media server, so it needs to be on most of the time. One of them is an OLED so I get it them to sleep after 5 minutes of inactivity. I use powercfg -requests to see what is preventing them from turning off and for the last couple of months I have been finding that MoUsoCoreWorker.exe is the thing causing the issue.I have tried powercfg /requestsoverride process MoUsoCoreWorker.exe execution which does nothing. I have tried adjusting my active hours, but that also seems to not matter, just because I’m asleep/way from the computer does not mean this is ha

Should MoUsoCoreWorker.exe preventing sleep be ignored?
I have seen several threads here complaining about this
Code:I don’t take that as something to get rid of but a warning that there is a problem with Windows updates
I just got that and then went into Windows Update
All seemed OK but based on past experience I knew there was something wrong with Windows Updates
I then restarted the Windows Update serviceI then retried Windows Update again
That showed there actually was a problem with Windows Update.
If we configured Windows so that MoUsoCoreWorker.exe no longer prevented sleep how are we to know when there is a problem with Windows Update?
In other words shouldn’t we take this more seriously and listen to what Windows is telling us instead of trying to hide it?

How to Fix MoUSO Core Worker Process (MoUsoCoreWorker.exe) Preventing Sleep on Windows 11
Many users have complained that their computers won’t sleep because MoUsoCoreWorker.exe is keeping the PC awake. This article will discuss this problem in more detail and provide several ways to fix it.
Upon running the POWERCFG -requests report, users see that it’s the MoUsoCoreWorker.exe process that keeps their computers awake. For some users, the computer keeps cycling between sleep and waking up.
MoUsoCoreWorker.exe preventing sleep is a problem that goes back to Windows 10 and is carried over to Windows 11. Unfortunately, Microsoft never fixed this bug.
What is MoUSO Core Worker Process?
MoUSO Core Worker Process is an Update Session Orchestrator (USO) that manages update sessions. It decides which updates must be installed first and which can be done later. It protects Windows from potential threats when updating and resolves issues that may prevent Windows from updating.
Depending on your system’s power configuration, it will appear as either MoUsoCoreWorker.exe or USOCoreWorker.exe.
Why Is MoUsoCoreWorker.exe Keeping My Computer Awake?
Since MoUsoCoreWorker.exe is responsible for managing system updates, it will prevent your PC from going to sleep unless all pending updates are installed.
In addition, misconfigured power settings and third-party applications (like GoodSync) may also trigger this issue.
Before trying our fixes, here are some tips:
- Update your Windows 11/10 operating system to the latest build.
- Run the Windows Update troubleshooter and Power troubleshooter.
- Restart the Windows Update Service.
- Close or uninstall third-party apps (particularly syncing applications like GoodSync) that interfere with MoUsoCoreWorker.exe.
If none of our tips resolve the issue, close Microsoft Edge and make sure that no processes related to it are running. You can check for and close Microsoft Edge-related processes using Task Manager. Then, try the methods below.

Привет, друзья. Windows 10 не переходит в спящий режим – с такой проблемой наверняка сталкивались многие из вас, кто давно работает с актуальной операционной системой от Microsoft. Операционная система может именно не уходить в сон, когда наступает время бездействия, назначенное в схеме электропитания, либо указанное нами в таймере выключения компьютера. А может уходить в сон, как и полагается, но потом сама произвольно выходить из него. Это две разные неполадки компьютера, но у них могут быть одинаковые причины и решения. Давайте же комплексно рассмотрим эти причины и поговорим об их устранении.
Windows 10 не переходит в спящий режим
Настройки сна
Первое, что нужно проверить – это системные настройки сна. Запускаем приложение «Параметры», идём по пути «Система > Питание и спящий режим». Здесь смотрим, выставлено ли вообще время погружения компьютера в спящий режим, не стоит ли значение «Никогда».
Если время погружения в сон выставлено, следующее, что нужно сделать – это проверить, наш компьютер не уходит в сон, либо он уходит, но потом сразу же или через какое-то время произвольно выходит из сна. Для этого выставляем в этих настройках минимальное значение времени погружения в сон, можно, например, 1 минуту. Далее ждём и наблюдаем, нам нужен точный диагноз проблемы.
Сброс параметров схемы электропитания
Устранение неполадок питания Windows 10
Если Windows 10 не переходит в спящий режим, при любом раскладе прибегнем к системному устранению неполадок питания. В приложении «Параметры» идём по пути «Обновление и безопасность > Устранение неполадок». Жмём «Дополнительные средства устранения неполадок».
Выбираем «Питание», жмём «Запустить средство устранения неполадок».
И следуем пошаговому мастеру средства. В моём случае оно выявило якобы неэффективную схему электропитания, всё это чушь, я пропускаю это исправление.
Вот и всё, в окошке диагностики средство отчиталось, что оно само исправило значение минимального состояния процессора. В моём случае это никакого отношения к режиму сна не имеет, возможно, в вашем случае будет какой-то результат.
Подключённая периферия
Подключённая к ПК или ноутбуку периферия типа внешних жёстких дисков, камер, микрофонов и т.п. может быть причиной и того, что компьютер не уходит в сон, и того, что он уходит, но потом произвольно пробуждается. Нужно отследить поведение компьютера в этом плане в условиях отключённой всей этой периферии. Если при отключённой периферии всё нормально, нужно далее по одному подключать эти устройства и тестировать погружение компьютера в сон. Ну и затем уже необходимо с причинным устройством разбираться отдельно, в частности, обновить или переустановить его драйвер. Если и после обновления или переустановки драйвера устройство продолжает быть причиной проблемы, необходимо удалить из операционной системы его старые версии драйвера. Как это делается, друзья, смотрите в статье «Как удалить неиспользуемые драйвера».
Драйвера видео- и аудиокарты
Причиной того, что Windows 10 не переходит в спящий режим, могут быть драйвера некоторых внутренних устройств — видео- и аудиокарты компьютера. Здесь также необходимо обновить или переустановить их драйвера, а также удалить неиспользуемые драйвера других карт, если таковые подключались ранее. Для удаления неиспользуемых драйверов смотрите статью по ссылке выше. А как правильно удалять драйвера видеокарт, смотрите статьи:
Мешающие сну программы и системные службы
Препятствовать как погружению компьютера в сон, так и произвольному выходу из сна может активность каких-то сторонних программ или системных служб Windows 10. Выявить эти программы можно следующим образом. Жмём клавиши Win+X, в меню выбираем запуск PowerShell от имени администратора.
Вводим команду:
powercfg -requests
И смотрим, нет ли в перечне ПО со статусом «Выполнение».
Если выполняемые программы есть, то нужно закрыть их и отследить, уходит ли компьютер в сон без их активности. Если причина — они, соответственно, нужно разбираться отдельно с этими программами. Но, друзья, обратите внимание, в моём случае выполняется некий процесс MoUsoCoreWorker.exe. Юзаем Интернет и узнаём, что это рабочий процесс, связанный с обновлением Windows 10. И в версии 2004 он может вызывать произвольные пробуждения компьютера. Это баг самой операционной системы, и вроде как Microsoft пыталась устранить эту проблему, написала патч исправления, но всё равно у многих пользователей проблема осталась. В качестве решения предлагается остановка службы центра обновления. Жмём Win+R, запускаем:
services.msc
Открываем службу центра обновления.
Жмём «Остановить».
И перезагружаем компьютер.
***
Вот это основные причины, почему Windows 10 не переходит в спящий режим, теперь давайте отдельно поговорим о проблеме, когда система в сон уходит, но потом произвольно из него выходит.
Как узнать, что именно будит компьютер
Первым делом необходимо выяснить, что именно будит компьютер. Для этого мы запускаем консоль управления компьютером, вводим в системный поиск «Управление компьютером». В консоли слева кликаем пункт «Просмотр событий» и далее раскрываем путь «Журналы Windows > Система». Справа консоли сортируем события по источнику. И просматриваем все, у которых источник Power-Troubleshooter, т.е. это системное событие выхода из сна. Каждое событие будет содержать указание на источник выхода из сна. И его нужно сопоставить со временем выхода из сна, было ли это произвольное действие компьютера, либо мы сами пробудили его. Вот, например, в моём случае источником выхода из сна является некое устройство USB Root Hub. Это USB-мышь, и в моём случае она не сама пробудила компьютер, а это были мои действия.
В качестве источника выхода могут быть указаны не только устройства компьютера, пробуждающие компьютер, но также таймер пробуждения какого-то задания.
Друзья, таймер пробуждения может вывести компьютер из сна для выполнения какой-то задачи – автоматического системного обслуживания или настроенных в планировщике Windows 10 задач. Сторонние программы могут задействовать таймеры пробуждения. Здесь можно поступить по-разному. Вы можете отключить автоматическое обслуживание Windows 10 вовсе, либо просто запретить этому процессу пробуждать компьютер. Можете отследить задание в планировщике, регулярно выводящее компьютер из сна, и запретить ему это делать или отключить такое задание вовсе. А можете решить вопрос одним махом — отключить таймеры пробуждения, и тогда ни одна запланированная задача не сможет пробудить ваш компьютер.
Отключение таймеров пробуждения
Для отключения таймеров пробуждения отправляемся в настройки схемы электропитания, как мы это делали во втором пункте статьи при сбросе параметров схемы электропитания в дефолт. Кликам «Изменить дополнительные параметры питания». Раскрываем «Сон», в пункте «Разрешить таймеры пробуждения» выставляем либо «Отключить», либо «Только важные таймеры». Жмём «Применить».
Устройства, которым разрешено выводить компьютер из сна
Если по итогам исследования просмотра событий оказывается, что источником произвольного выхода компьютера из сна являются какие-то устройства – мышь, клавиатура, сетевая карта и т.п., нужно разобраться с ними. Возможно, у вас ПК стоит на шаткой поверхности, и клавиатура или мышь реагируют на вибрации окружающей среды. Возможно, в ваше отсутствие ваши домашние питомцы – кошка или собака – играют с клавиатурой или мышью. А, возможно, у вас в BIOS активна Wake-On-Lan – функция пробуждения компьютера по сети, и ваша сетевая карта во время сна получает сетевые пакеты. В таком случае этим устройствам можно запретить выводить компьютер из сна. Отправляемся в диспетчер устройств, можем его открыть с помощью упомянутого выше меню «Win+X». Двойным кликом открываем свойства причинного устройства. Идём во вкладку «Управление электропитанием». Снимаем галочку «Разрешать этому устройству выводить компьютер из ждущего режима». Жмём «Ок».
Аппаратные неполадки
Ну и в завершение поговорим об аппаратных неполадках компьютера. Причиной и того, что Windows 10 не переходит в спящий режим, и что система произвольно выходит из сна, могут быть проблемы с материнской платой, блоком питания, возможно, других внутренних устройств ПК или ноутбука. Чтобы проверить это, лично я бы установил на второй раздел диска Windows 7, чистую, не кастомную, не ставил бы никакого стороннего софта. И проверил бы, как со сном работает чистая «Семёрка». Возможно, у вас есть другие причины подозревать аппаратные неполадки, тогда ни в какой подобной диагностике нет сенса. Просто нужно обратиться к компьютерному мастеру или в сервисный центр.
Issue: Hello. I don’t know how to deal with this issue I have. My computer is waking up from sleep all the time. Then it goes back to sleep shortly after. I think MoUsoCoreWorker.exe prevents Windows from going to sleep normally because the process is running in the background. Can you offer any solution for this? I am afraid to terminate the process without any knowledge. Help!
Solved Answer
MoUsoCoreWorker.exe prevents Windows from going to sleep seems an annoying issue because the computer might encounter additional problems when the sleep function is not working properly. This particular problem has been reported[1], and it seems that the common fact about all the user complaints involves Windows 10 update.[2]
It is not new that Windows operating system updates trigger issues with various everyday processes. Users claim that their devices keep waking up from sleep and that MoUsoCoreWorker.exe prevents Windows from going to sleep in particular. There might be a few system tweaks and changes, but the issue can be fixed.
This USO core worker process is related to Windows Update and can trigger wakeups after you update the machine to the latest OS version. An additional reason that can cause this sleep issue is corrupt or misconfigured settings. You can also find some third-party applications triggering issues, so changing preferences or removing the conflicting application can help fix MoUsoCoreWorker.exe prevents Windows from going to sleep.
You can find some particular files or components damaged on the machine due to buggy updates, incorrect installations, or even after the cyber threat infection.[3] Users encounter the problem when the systems not going to sleep. Often sleep diagnoses get applied, so people can determine that they need to fix the MoUsoCoreWorker.exe issue since this file is the one that prevents Windows from going to sleep.
When people encounter the issue with the device sleep and wakeup, the system sleep diagnostics command reveals that MoUsoCoreWorker.exe prevents Windows from going to sleep in particular. The reason why this file keeps the PC out of sleep is the process that cannot find the update status information. It tries to get information about the update and repeats the procedure over and over again.

It will allow you to connect to the internet while being completely anonymous by encrypting all information, prevent trackers, ads, as well as malicious content. Most importantly, you will stop the illegal surveillance activities that NSA and other governmental institutions are performing behind your back.
Recover your lost files quickly
Unforeseen circumstances can happen at any time while using the computer: it can turn off due to a power cut, a Blue Screen of Death (BSoD) can occur, or random Windows updates can the machine when you went away for a few minutes. As a result, your schoolwork, important documents, and other data might be lost. To recover lost files, you can use Data Recovery Pro – it searches through copies of files that are still available on your hard drive and retrieves them quickly.
Your system may fail to sleep due to MoUsoCoreWorker.exe if you have not updated the Windows of your system to the latest build. Moreover, corrupt/misconfigured power settings or conflicting third-party applications (like GoodSync) may also cause the error under discussion.
The user encounters the issue when the system does not go to sleep on the defined time but stays awake. For some users, the system keeps on cycling between sleep and waking up. When the user executes the powercfg /systemsleepdiagnostics command, MoUSO Core Worker Process (MoUsoCoreWorker.exe) is found to be responsible for this behavior.
Before moving on with the solutions, make sure the Edge browser is totally closed and no process related to it is operating in the Task Manager of your system.
Solution 1: Uninstall/Disable the Conflicting Applications
Your system may fail to sleep if any of your applications (especially syncing applications) keep the MoUSO Core Worker Process busy (which prevents the system from sleeping). In this context, either disabling these applications or uninstalling them may solve the problem. GoodSync is an application known to cause the issue.
- Click on the Windows button and click on Gear/Settings.
Open Windows Settings - Now, open Apps and then expand GoodSync.
- Then click on Uninstall and then confirm to uninstall GoodSync.
Uninstall GoodSync - Now follow the prompts on the screen to uninstall GoodSync. If you do not want to uninstall GoodSync, then disable its syncing operation (not set to “On Schedule” & “Run without User Interface (Unattended)”) and completely exit it. Also, uninstall/disable all other conflicting applications (that you think are creating the problem).
- Then restart your system and upon restart, check if your system’s sleep issue is resolved.
Solution 2: Disable Wake Timers of Your System
Your system may not go to sleep if its wake timers are hindering in the sleep operation. In this case, disabling the wake timers of your system may solve the problem.
- Press the Windows + Q keys to open the Windows Search and type Control Panel. Now, in the search results displayed, click on the Control Panel.
Open Control Panel - Now open Hardware & Sound and select Power Options.
Open Power Options - Then click on Change Plan Settings and click on the Change Advanced Power Settings.
Change Advanced Power Settings - Now click on the plus sign to open the Sleep settings and then expand Allow Wake Timers.
- Then disable the wake-up timers for both “On Battery” and “Plugged in” and restart your system.
Disable Automatic Wake Timers - Upon restart, check if the sleep issue of your system is resolved.
Solution 3: Disable Update Orchestrator (UOS) Service
