Background

I needed to see why a family member’s computer was using so much memory.

Launched Task Manager and was familiar with most of the processes.

USO Core Worker Process

The lone process I was not familiar with is “usocoreworker.exe”.

Tab – General
- Properties
  - Folder:- C:\Windows\System32
Tab – Details
- Properties
  - File Description:- USO Core Worker Process
  - Product Name:- Microsoft Windows Operating System

Google on “USO Core Worker Process“.

Here is a brief outline:-

USO stands for Update Session Orchestrator (a new tool to coordinate and manage update sessions), a new Windows Update Agent.
The actual file names can be:-
- usocoreworker.exe
- usoclient.exe

On Reddit, contributor Graciliano5678, said :-

Disable Delivery Optimisation and make sure all your updates are installed, and restart. It should go down and stay down.

I tried taking it a bit further.

Upon trying to disable the service, received a warning.

The warning stated, “Access is denied”.

Returned back to Task Manager.

Thankfully, the application is no longer using as much memory.

Unfortunately, one will have to apply this remediation occasionally.

The “Delivery Optimization” service is an essential part of Microsoft Windows.
