What Is MoUSO Core Worker Process? A Complete Guide

The MoUSO Core Worker Process is a PHP-based core script client on the server network, which is specifically intended for the execution of commands on the servers. For the purposes of running these commands, CPU and disk resources are utilized.

Because of malware, hacking, or any other such issue, the MoUSO Core Worker Process does not consume large amounts of CPU/disk. In this article, I will explain how to stop or prevent the “MoUSO Core Worker Process” in Android.

The MoUSO Core Worker Process: What Is It?

The term USO in the process name refers to the Update Session Orchestrator. The Microsoft documentation indicates that it is one of the built-in components of the Unified Update Platform (UUP), Microsoft’s update model introduced with Windows 10.

A MoUSO Core Worker Process is responsible for managing the order in which operating system updates are downloaded and installed. Essentially, this process controls the order in which updates are downloaded and installed.

As a default, the MoUSO Core Worker Process begins processing only when Windows searches for updates. However, it is possible for it to remain active for a significant length of time without apparent cause. The result is excessive CPU and RAM consumption, which causes your computer to hang. At this point, the situation becomes problematic.

The following suggestions can be used if the MoUSO Core Worker Process consumes too much CPU or RAM.

Verify the Authenticity of the Process

To begin with, it is important to confirm that the executable is from Microsoft rather than a Trojan installed by a cybercriminal. Most hackers use the same names as the original processes, which makes it difficult for them to be identified.

The following steps can be used to verify the authenticity of any executable file:

  • The Task Manager can be accessed by right-clicking the Windows Start button.
  • Make a right-click on the MoUSO Core Worker Process and select Properties.
  • When you open the Properties window, click on the General tab, and then click on the Location button.
  • Copy the path and paste it into the address bar of File Explorer.
  • The executable file for the process can be found here.
  • Make a right-click on the file and select Properties.
  • Select the Details tab from the Properties window.
  • Please confirm that “Microsoft Corporation. All rights reserved” is written next to the Copyright.

Restart the MoUSO Process

The old-school technique of restarting the program to resolve issues may also be effective here. Therefore, it is recommended that you start over before making any significant changes to the process. Following are the steps you can follow to restart the process:

  • Select Task Manager from the Windows Start menu by right-clicking.
  • Using the right-click menu, select End task for the MoUSO Core Worker Process.

In order to restart the process, restart your computer. The following fix may be helpful if restarting the process does not result in a reduction of CPU or RAM consumption.

Check for Available Updates and Install or Pause Them

The MoUSO Core Worker Process will be relieved of some of its burden if updates are manually installed. In this way, the resource consumption of the process will be reduced. Therefore, it is recommended that you check for updates and allow Windows to install them.

Additionally, you should check for and install any optional Windows updates if they are available. In the event that installing automatic and optional updates does not resolve the issue, you may wish to pause the Windows updates and check if that resolves the problem.

Run the Windows Update Troubleshooter

There is a handy Windows Update troubleshooter included in Windows that can assist you with any issues that relate to Windows updates. Therefore, run the troubleshooter to determine if it can help identify the problem and resolve the resource consumption issue.

The following steps should be followed to run the troubleshooter:

  • Select Settings by right-clicking the Windows Start button.
  • Go to the Update & Security section.
  • The Troubleshoot tab can be found in the left sidebar.
  • Then, click Additional troubleshooters on the right side of the screen.
  • The Windows Update option can be found under getting started.
  • Run the troubleshooter by clicking on the Run button.

Ensure that the Windows Update troubleshooter has identified any problems and reduced the consumption of system resources.

Disable Delivery Optimization

By utilizing Delivery Optimization, Windows users can download updates or parts of updates from other computers on the same network. By doing so, new updates are more easily accessible.

As USO Core Worker Process manages Windows updates and their installation, downloading updates from other machines can significantly increase resource requirements.

The best way to rule out this possibility is to disable Delivery Optimization. For this purpose, go to the Windows Settings app > Update & Security > Advanced Options > Delivery Optimization. To turn it off, turn the toggle next to Allow downloads from other computers to the left.

Restart Relevant Windows Update Services

There is a good chance that resuming the services in the Windows operating system will resolve common problems. In order to resolve the issue, you will need to restart Windows Update and the Update Orchestrator Service.

Following are the steps you can take to restart the Windows Update service:

  • By typing “Services” into the Windows search bar, you will be directed to the Services app.
  • The Windows Update service can be found in the right-hand pane.
  • By right-clicking it and selecting Restart, you will be able to restart it.

As a next step, restart the Update Orchestrator Service by following the steps below:

  • Locate the Update Orchestrator Service in the Services app.
  • Restart the computer by right-clicking on it.

Does the process still consume too much power? It is then necessary to disable the service.

Disable the Update Orchestrator Service

The last resort is to disable the Update Orchestrator Service in order to terminate the MoUSO Core Worker Process. For the purpose of disabling it, follow the steps below:

  • Click on the Services app.
  • The Update Orchestrator Service can be found within the Service app.
  • By right-clicking on it, you can select Properties.
  • You can disable the startup type by selecting Disabled from the dropdown next to it.
  • After you have completed this step, click Apply and then OK.

By disabling this service, the MoUSO Core Worker Process will be stopped. In the event that it does not work, you can return to Task Manager and terminate it there. By disabling the service, the service will never again be displayed in Task Manager.
