What is SkypeService.exe?
skype-service-exe is the background service component of Skype for Desktop that runs as SkypeService.exe. It manages core chat signaling, presence updates, notification delivery, and coordination of media sessions, while the main UI (Skype.exe) handles user interaction. This separation improves responsiveness and keeps messaging and presence snappy even when the window isn't focused.
This multi-process design lets SkypeService.exe run separately from the UI, enabling faster response to network events and safer handling of messaging, presence, and updates. It communicates with Skype.exe to coordinate calls and data exchange.
Quick Fact: Skype pioneered a lightweight background service to keep presence and notifications responsive even when the UI is minimized.
