您可能会注意到 Windows PC任务管理器(Task Manager)中有一个名为MoUsoCoreWorker.exe的进程。这个过程是什么？安全吗？你应该尝试删除它吗？如果它显示CPU使用率很高，你应该怎么做？
任何Windows PC 都有一堆在后台安静运行的进程。大多数这些进程在操作系统中扮演关键角色并使用最少的资源。还有一些，例如MoUsoCoreWorker.exe，是属于Windows的官方进程。
什么是 MoUsoCoreWorker.exe？
MoUsoCoreWorker.exe是经过认证的Windows进程。作为Windows 更新(Windows Update)服务的核心部分，其名称中的“Uso”部分代表更新会话编排(Update Session Orchestrator)器。与大多数Windows服务一样，它位于C:\Windows\System32中。
在早期版本的Microsoft Windows中，它的角色是由 wuauclt.exe 执行的。从Windows 10开始，更新(Update)界面升级为统一更新平台(Unified Update Platform)( UUP )，将 wuauclt.exe 替换为MoUsoCoreWorker.exe。
该过程旨在跟踪Windows 更新(Windows Updates)，安排在您的计算机上安装必要的更新。这意味着即使没有安装更新，您也会看到该进程正在运行——MoUsoCoreWorker 可能正在检查更新。
MoUsoCoreWorker.exe 是恶意软件吗？
MoUsoCoreWorker.exe是完全安全的。它是执行Windows 10或 11 更新过程的众多过程之一，因此是Microsoft发布的经过验证的过程。
它的名字可能看起来很奇怪，但这个过程没有什么好害怕的。高级(Power)用户可能会注意到它发出连接请求，但这也是正常的。它在后台运行，定期检查更新。
如何修复 MoUsoCoreWorker.exe 高 CPU 使用率(Fix MoUsoCoreWorker.exe High CPU Usage)？
与所有Windows服务一样，此更新协调器服务并非没有问题。有些人报告说在任务管理器中看到(Task Manager)USOCoreWorker.exe具有非常高的CPU或RAM使用率，从而降低了系统速度。
稍后更新中修复的另一个常见问题是 usoclient.exe（同一服务的另一个组件）干扰睡眠模式。不知何故，即使将电源(Power) 选项(Options)设置为使系统自动进入睡眠状态，
该过程也会反复唤醒 PC 。
虽然这些问题已在更高版本的Windows 10中得到解决，但仍然缺少更新的用户可能会看到此服务存在问题。在这种情况下，只需重新启动Windows 更新服务(Windows Update Service)即可使其再次正常运行。
要重新启动Windows 更新服务(Windows Update Service)：
- 按 Start(Press Start)，搜索Services，然后启动Services应用程序。
- 服务(Services)应用程序显示您计算机上安装的所有服务。您可以从此界面启动、停止(Stop)或重新启动任何服务，并阅读有关它们的更多信息。(Restart)现在，单击任何条目，然后按“w”键快速导航到以该字母开头的服务。向下滚动(Scroll)，直到找到 Windows Update。
- 右键单击(Right-click)Windows 更新(Windows Update)服务并在弹出菜单中选择停止。(Stop)服务停止后，再次右键单击Windows 更新(Windows Update)，这一次，选择开始(Start)选项。
这会强制Windows 更新(Windows Update)重新开始，打破任何可能阻止MoUsoCoreWorker.exe正常运行的卡住更新。
你应该卸载MoUsoCoreWorker.exe吗？
您无法卸载MoUsoCoreWorker，因为它是Windows的核心组件。该进程负责检测和安排Windows 更新(Windows Updates)，这对于保持计算机正常运行至关重要。删除MoUsoCoreWorker会导致Windows安装更新的方式发生冲突，从而威胁系统稳定性。
该过程在后台无害地运行，对系统的影响最小。如果您发现CPU或RAM使用率较高，则应重新启动Windows Update服务并安装最新更新。
What Is MoUsoCoreWorker.exe and Is It Safe?
You mіght notice a procesѕ in уоυr Windows PC Task Manager named MoUsoCoreWorker.exe. What is this process? Is it safe? Should you try to remove it? What should you do if it shows high CPU usage?
Any Windows PC has a bunch of processes running quietly in the background. Most of these processes fulfill critical roles in the operating system and use minimal resources. And some, like MoUsoCoreWorker.exe, are official processes that are part of Windows.
What Is MoUsoCoreWorker.exe?
MoUsoCoreWorker.exe is a certified Windows process. A core part of the Windows Update service, the “Uso” part of its name stands for Update Session Orchestrator. Like most Windows services, it resides in C:\Windows\System32.
In earlier versions of Microsoft Windows, its role was carried out by wuauclt.exe. Starting with Windows 10, the Update interface was upgraded to Unified Update Platform (UUP), replacing wuauclt.exe with MoUsoCoreWorker.exe.
The process is meant to keep track of Windows Updates, scheduling the installation of necessary updates on your computer. This means you will see the process running even when an update is not being installed—MoUsoCoreWorker might be checking for updates.
Is MoUsoCoreWorker.exe Malware?
MoUsoCoreWorker.exe is entirely safe. It is one of the many processes that carry out the Windows 10 or 11 update process and, as such, is a verified process published by Microsoft.
Its name might look weird, but there is nothing to fear from this process. Power users might notice it making connection requests, but that’s normal too. It runs in the background, periodically checking for updates.
How to Fix MoUsoCoreWorker.exe High CPU Usage?
Like all Windows services, this update orchestrator service is not without issues. Some people report seeing USOCoreWorker.exe in the Task Manager with very high CPU or RAM usage, slowing down the system.
Another common problem fixed in later updates is the usoclient.exe (another component of the same service) interfering with sleep mode. Somehow the process was waking up the PC repeatedly even when the Power Options were set to put the system to sleep automatically.
While these issues were ironed out in later versions of Windows 10, users still missing the updates might see problems with this service. In that case, simply restart the Windows Update Service to get it working smoothly again.
To restart the Windows Update Service:
- Press Start, search for Services, and launch the Services app.
- The Services app displays all the services installed on your computer. You can Start, Stop, or Restart any services from this interface, as well as read more about them. For now, click on any entry and then hit the ‘w’ key to navigate quickly to the services beginning with that letter. Scroll down until you find Windows Update.
- Right-click the Windows Update service and select Stop on the pop-up menu. After the service stops, right-click Windows Update again and this time, select the Start option.
This forces Windows Update to start over, breaking past any stuck updates that might prevent MoUsoCoreWorker.exe from functioning correctly.
Should You Uninstall MoUsoCoreWorker.exe?
You cannot uninstall MoUsoCoreWorker, since it is a core component of Windows. The process is responsible for detecting and scheduling Windows Updates, which is essential to keep your computer running correctly. Removing MoUsoCoreWorker would cause conflicts in how Windows installs its updates, threatening system stability.
The process runs innocuously in the background, with minimal system impact. If you see a high CPU or RAM usage, you should restart the Windows Update service and install the latest updates.
