In the Windows operating system, one often finds unknown processes running in the background. One of those processes, which is in the spotlight for the first time, is the MoUso Core Worker Process.

If you've done a Task Manager check and you've seen this process using CPU or waking your PC out of sleep, this is an article for you. Let's go in-depth about what the MoUso Core Worker Process is, why it's running, and if you should be worried about it.

What is MoUso Core Worker Process?

 The MoUso Core Worker Process (MoUsoCoreWorker.exe) is a system process provided by Microsoft as a component of the Windows Update infrastructure. Its full name is the Modern Update Session Orchestrator and is responsible for the way Windows downloads and applies updates.

In a way, it is an intermediary between the Windows Update service and your machine, managing to get the updates done in an efficient manner.

It supersedes the older "wuauclt.exe" and offers more control over update downloading, scheduling, and installation.

MoUso Core Worker Process is not a virus

 One of the most often asked questions is: "Is MoUsoCoreWorker.exe a virus?"

The simple answer is no, it is not malware or a virus. It is a genuine Microsoft process. But, as with any executable file, it is possible for malicious applications to copy it. If the file is in any directory other than C:\Windows\System32, you need to run a virus scan.

Why is MoUsoCoreWorker.exe Waking My PC

 A lot of users complain that their PC is waking up from sleep mode automatically. Usually, the culprit is the MoUso Core Worker Process. Here is how

• It periodically checks for pending updates.
• If an update is pending or requires a reboot, it may wake the PC.
• It occurs most often if the setting of "Wake the computer to run this task" in Task Scheduler is turned on.

It is possible to disable this behavior by altering the task scheduler options for update-related tasks or by turning off wake timers.
