The fact that you are here, reading this article, proves that you too are pondering over this new term of USO Core Worker Process. So, what is this USO Core Worker Process? How does it affect your computer system? In this article, we will be busting some myths about this process. Let us now get on with what usocoreworker.exe really is:

USO Core Worker Process (usocoreworker.exe) on Windows 10 Version 1903

First of all, you need to know the full form of USO. It stands for Update Session Orchestrator. The usocoreworker.exe is a new Update Agent introduced by Windows that works as a coordinator to manage the update sessions. You must be knowing that .exe is an extension for the executable files. Microsoft’s Windows Operating System owns the USO process. It is basically a process to replace the older Windows Update agent.

The USO process works in phases, or rather we can call them stages:

  1. The first phase is the Scan phase, where it scans for the available and required updates.
  2. The second phase is the Download phase. The USO process in this phase downloads the updates that came into view after the scan.
  3. The third phase is the Install phase. The downloaded updates are installed at this stage of the USO process.
  4. The fourth and last phase is to Commit. At this stage, the system commits all the changes caused by installing the updates.

Before this USO was introduced, Windows inculcated wuauclt.exe, and the detect now command that was used to schedule updates on the older versions. But with the Windows 10 1903, this command was discarded. The traditional settings were moved from the control panel to the System Settings in this update. The usoclient.exe has replaced the wuauclt.exe. From and after 1903, the wuauclt has been removed, and you can no longer use this command. Windows now use other tools to scan for updates and install them, like usoclient.exe, usocoreworker.exe, usopi.dll, usocoreps.dll, and usosvc.dll. These processes are not only used for scans and install but also when Windows is about to add new features.

Microsoft released these tools without any instruction manual and document. These were released with just a note that – ‘These commands are not valid outside the Windows Operating System.’ This means that no one can access the use of the client or the USO Core Worker Process outside the operating system directly.

But there is no meaning in going too deep over this topic. In short, we can understand the USO Core Worker Process (usocoreworker.exe) as a Windows’ system process, which is related to the administration and supervision of Windows update scanning and installations. This process also works when new features are introduced in the Operating System. It hardly uses any of your system memory and never bothers you with any notification or pop-up. It infrequently causes any issue. So, you can easily to afford to ignore it and let this process do the job without ever bothering you.
