Does your computer turn on automatically even while it’s in sleep mode? If so, probably the MoUSO Core Worker Process is responsible for this. It’s a process that automatically runs in the background while checking or installing a Windows update.
The MoUSO Core Worker Process is able to turn on your computer automatically from sleep mode if it finds any problems while installing an update. It can even consume high RAM and CPU usage.
However, if you want to disable this process but don’t know whether it’s safe, this guide will cover everything you need to know. Furthermore, if it’s consuming too much of your resources, we’ll provide solutions to fix it.
What is the MoUSO Core Worker Process?
MoUSO Core Worker Process is an Update Session Orchestrator (USO) of Microsoft that helps to manage the update sessions of Windows OS. Microsoft included this process from Windows 10 version 1903.
Managing the update session includes resolving problems that can interrupt the Windows update process. It also keeps Windows safe from any threats while performing an update.
MoUSO Core Worker Process automatically gets activated in the background whenever Windows checks for updates. It usually doesn’t affect any other process that is currently running.
However, sometimes it remains active for a long without any valid reason, which causes high CPU or RAM consumption of your device. As a result, it wakes up your system from sleep mode and might make it slow.
Is the MoUSO Core Worker Process a Malware?
MoUSO Core Worker Process is a completely safe program made by Microsoft. It comes with Windows when you install it on your device. This means you don’t need to worry that this program will harm your system.
However, as the program uses excessive CPU or disk space, it could cause harm if you allow the process to run for a long time. According to some users, it might harm your SSD drive in extreme cases.
