MoUSO Core Worker Process (он же MoUsoCoreWorker.exe) периодически вызывает нагрузку на компьютер. Многие пользователи, заприметив данный процесс в списках Диспетчера задач, задаются вопросом: а не вирус ли это? В конце концов, перед нами какой-то непонятный процесс, который еще и потребляет для своей работы — хоть и не всегда — n-ную часть системных ресурсов.
В сегодняшней статье о том, что собой представляет процесс MoUSO Core Worker и стоит ли о нем переживать.
MoUSO Core Worker Process — что это за процесс?
MoUSO Core Worker Process — один из основных компонентов платформы Unified Update Platform (UUP). В активный обиход платформа вошла еще на ранних этапах жизни Windows 10. Согласно Майкрософт, UUP многократно ускоряет и оптимизирует процесс обновления поддерживаемых операционных систем. Сам же процесс MoUSO Core Worker ответствен за проверку наличия, загрузку и установку обновлений для ОС Windows 10 и Windows 11. Проще говоря, мы имеем дело с одной из ключевых служб Центра обновления.
Проверить легитимность этого процесса довольно легко: кликните ПКМ на MoUsoCoreWorker.exe и выберите «Открыть расположение файла». Если вы оказались в папке \Windows\UUS\amd64, то все в порядке — это никакой не вирус и вредоносное ПО. Если же вас перенесло в какое-то иное расположение в системе, в срочном порядке просканируйте исполняемый файл доступным антивирусом.
MoUSO Core Worker грузит процессор — как исправить?
Важно отметить, что процесс MoUSO Core Worker активизируется только во время поиска и установки обновления для Windows 10/11. В зависимости от ПК нагрузка может достигать высоких отметок, однако она не продолжительна: работа процесса не должна помешать работе системы. Как и многие другие службы и процессы, пользователь может завершить работу MoUSO Core Worker, но в этом нет смысла, т.к. он снова будет запущен сразу либо при следующей проверке наличия обновлений.
Пожалуй, единственный способ сделать так, чтобы рассматриваемый процесс перестал чрезмерно нагружать компьютер — это дождаться окончания обновления Windows. Совет особо актуален для владельцев машин, которые не могут похвастаться высокой производительностью. Подождите завершения загрузки/установки обновлений и MoUSO Core Worker Process не только перестанет «съедать» ресурсы, но и исчезнет из Диспетчера задач.
Если вы из тех пользователей, которые, заметив всплеск нагрузки, заглядывают в диспетчер задач, с большой вероятностью однажды вы заметите, что нагрузка на процессор и высокое потребление памяти вызвано процессом MoUSO Core Worker Process и соответствующим ему файлу MoUsoCoreWorker.exe.
Далее в статье подробно о том, что это за процесс, почему он может нагружать процессор или RAM и следует ли что-то предпринимать по этому поводу.
Назначение процесса MoUSO Core Worker Process
MoUsoCoreWorker.exe — один из компонентов унифицированной платформы обновлений Windows или Unified Update Platform (UUP). Впервые появился в Windows 10 (но не с самых первых версий), в Windows 11 в наличии сразу после релиза операционной системы.
UUP представляет собой новую архитектуру доставки и развертывания обновлений Windows, более подробно о которой, на английском, можно прочитать на официальном сайте Майкрософт.
В свою очередь, MoUSO Core Worker Process представляет собой процесс одного из компонентов этой платформы обновлений — Update Session Orchestrator (USO), что можно перевести как Оркестратор сессий обновлений и участвует в проверке наличия, загрузке и установке обновлений Windows 11 или Windows 10.
Что делать при высокой нагрузке из-за MoUsoCoreWorker.exe
При нормальной работе системы процесс MoUSO Core Worker появляется в диспетчере задач только в случаях, когда система выполняет какие-либо действия с обновлениями, что легко проверить, зайдя в Параметры и открыв раздел «Центр обновления Windows».
В некоторых случаях нагрузка может быть значительной, но как правило это непродолжительный процесс, завершения которого стоит дождаться: по завершении процесса установки обновлений всё придёт в норму.
При необходимости вы можете снять задачу MoUsoCoreWorker.exe в диспетчере задач, но процесс может запуститься снова, а скачивание и установка обновления начаться с самого начала.
Ещё один нюанс: MoUSO Core Worker может выводить компьютер или ноутбук из режима сна для установки обновлений. Лучше дождаться завершения процесса или, если это неприемлемо, отключить таймеры пробуждения, как это описывается в статье Что делать, если Windows сама включается или просыпается.
Может ли процесс MoUsoCoreWorker.exe вирусом? Теоретически, это возможно. Но если файл расположен в папке C:\Windows\UUS\amd64 и запускается при установке обновлений, то, похоже, это обычный системный файл Windows.
During a Windows update, your computer just started to slow down and you find that the process is consuming a lot of CPU and RAM? Here in a couple of minutes you will learn about what kind of file it is and how to make it so that it does not overload your computer.
What Is MoUSO Core Worker Process?
Windows contains many routines and files whose purpose we may not even know, but which are very important because they provide the work of all parts of this advanced operating system. One such file in Windows 10 and Windows 1 is musocoreworker.exe and it stands for Microsoft Update Session Orchestrator. This file is part of the UUP platform (Unified Update Platform), which is responsible for the stable implementation of periodic updates of the operating system.
Important tip! Viruses and trojans often mimic legitimate Microsoft file names, so it’s a good idea to make sure that a running file under the name is exactly the same file, and does not resemble it in name. Real Windows executables are signed by Microsoft. To verify the authenticity of the file, in the Task Manager, right-click on the MoUSO file and select Properties, and then in the General tab of the Properties window, copy the path next to Location and paste the copied path into the address bar of File Explorer. Also, to be sure, you can scan this file as you would any .exe file with the built-in Microsoft Defender/Windows Security scanning service. It’s very simple. Locate the file and right-click it > Scan with Microsoft Defender.
Locate the process executable, right-click on it and select Properties and open the Details tab. There should be an inscription: «Microsoft Corporation. All rights reserved«.
How to Fix MoUSOCoreWorker.exe
As we already mentioned, usually musocoreworker.exe is activated when there is a check for updates. But sometimes it may happen that after completing the check and installation of updates, the update does not start and the file continues to work. This leads to high RAM and disk usage, which naturally results in a significant slowdown in your PC.
Restart Windows Update
You can try restarting the update, and perhaps the glitch will disappear. You can restart the Windows Update service by writing Services in the Windows search bar > Windows Update. Right click on it > Restart.
It can also help further restarting the Update Orchestrator Service. You can find this service in the Services app.
Run Windows Update Troubleshooter
But what if that doesn’t help and the file continues to work stubbornly? Find and fix problems in updating the OS will help you the built-in Troubleshooter that Windows 11 is equipped with. To launch it, click Start and in the search bar write Settings and confirm this with the Enter key. In the list that appears, find the item Troubleshooting, and click on it. Here search for a troubleshooter labeled Windows Update.
In the older versions of Windows, right-click the Windows Start button and select Settings. In the Update & Security section, find the Troubleshooting tab and right click on Advanced Troubleshooters. Locate the Get Up and Running section and click on Windows Update > Run the troubleshooter.
Disable the Update Orchestrator Service
If all else fails and the glitch continues, you can completely cancel the update service and thus stop the MoUSO process. To do this, in the Services application, right-click on the Update Orchestrator option and select Properties > General > Startup Type > Disabled > Apply > OK.
