What is maxthon-service.exe?

maxthon-service.exe is the dedicated Windows service component for the Maxthon Cloud Browser. It runs in the background to support cloud sync, notifications, updates, and companion tasks, allowing the browser to function smoothly without requiring the foreground window to stay open.

Maxthon uses separate processes for core tasks and background operations. The service ensures data sync with the cloud, handles update checks, and provides tray notifications, even when the browser window isn't visible.
