What is MoUSO Core Worker Process? Is It Safe to REMOVE It?

If you’re like most Windows users, you have probably seen the MoUSO Core Worker Process running in your Task Manager and wondered what it is. This process is usually active when there is something related to a Windows update is running on your system.

In some cases, it can be safely removed from your system; in others, it is required for the proper functioning of Windows. In this article, we will explore what MoUSO Core Worker Process is and whether or not it can be safely removed from your system.

What is MoUSO Core Worker Process?

The MoUSO Core Worker Process is an Update Session Orchestrator (USO) provided by Microsoft to manage update sessions on the Windows operating system. This process is majorly responsible for fixing any problems that might prevent the Windows update.

When executing a Windows update, the MoUSO Core Worker also protects the system from potential dangers that might create hindrances in the Windows Update process. When Windows checks for updates, the process automatically gets activated in the background.

This process was first introduced in Windows 10 version 1903. So, if you’re using an earlier version of Windows 10, you may not see it in the Task Manager.

The MoUSO Core Worker Process has the capability to power on a computer from sleep if there are any problems while downloading or installing an update. However, sometimes it unnecessarily wakes up the system from sleep even though there is no system update going on. In the process, it would consume system power to find the update status.

During the Windows Update process, i.e., updating or checking for updates, the following executable and DLL files run in the background:

• USOCoreWorker.exe
• USOClient.exe
• USOapi.dll
• USOcoreps.dll
• USOsvc.dll

Is it Safe to Remove MoUSO Core Worker Process?

Yes, in some cases, it can be safely removed from your system. If you’re not planning to update your Windows operating system anytime soon or if you don’t want the process to unnecessarily wake up your computer from sleep, then you can disable this process.

However, if there is a Windows update going on and you remove this process from your system, it might create problems and may even prevent the Windows update from completing successfully.

So, it is advisable to leave the MoUSO Core Worker Process running on your system unless you’re sure that you won’t be needing it anytime soon.
