    Microsoft Copilot in Edge Browser answered:


    A **service worker** is a script that your browser runs in the background, separate from a web page. It helps manage things like caching and background tasks to make web apps work better, even offline.

    When you see a service worker process for the YouTube Music app in your Task Manager, it means that this script is running to handle tasks like:
    - **Caching music and other resources** so they load faster.
    - **Managing notifications** and background updates.
    - **Handling offline access**, so you can still use the app without an internet connection.

    In simple terms, the service worker helps the YouTube Music app run more smoothly and efficiently by taking care of these background tasks. If you notice it in Task Manager, it's just doing its job to improve your experience with the app⁴.
