The Creative Cloud desktop app has several individual components inside its user interface, such as the Apps tab, the Files tab, and the Discover tab. Adobe CEF helper is a process that renders these components of the Creative Cloud desktop app. Usually, there are multiple processes with this name running at the back end as we have divided the user interface in the different sections to monitor each process separately. If there's an issue in one component, CEF helper manages that individual component of the Creative Cloud desktop app without impacting other components. CEF helper is important to run the Creative Cloud desktop app.
