Are you having problems with a process that appears in Task Manager as MoUSO Core Worker Process, such as usocoreworker.exe, usoclient.exe, or USO Core Worker Process?
The MoUSO Core Worker Process, also known as MoUSOCoreWorker.exe, is a Microsoft process that assists the operating system in managing Windows update installation. Its moniker, “USO,” stands for “Update Session Orchestrator,” which pretty well covers up what it does.
If your computer keeps waking up from sleep, the MoUSO Core Worker Process might be at fault. Furthermore, the method may cause significant CPU or disk utilization. This can substantially slow down your computer and, if not addressed, may lead to more severe problems in the future.
