Fixes: Mouso Core Worker Process [2024]

Windows 10 users often encounter various system processes in their Task Manager, but one that frequently raises concerns is the MoUSO Core Worker Process, known technically as MoUSOCoreWorker.exe. This process is an integral part of the Microsoft Windows operating system, primarily tasked with managing the installation of Windows updates. The acronym “USO” stands for “Update Session Orchestrator,” which succinctly describes its function.

However, this process is not without its issues. Many users report that it can lead to high CPU or disk usage, and in some cases, it causes computers to wake up unexpectedly from sleep mode. Such problems can significantly slow down your computer and, if left unresolved, might lead to more severe issues.
