The service runs as a Windows service in session 0 and communicates with Microsoft servers using encrypted channels to sync messages, presence, and call setup, while isolating UI for stability.

How to Tell if skype-service is Legitimate or Malware
- File Location:: Must be in C:\Program Files (x86)\Microsoft\Skype for Desktop\SkypeService.exe or C:\Program Files\Microsoft\Skype for Desktop\SkypeService.exe. Other paths are suspicious.
- Digital Signature:: Right-click the file in Explorer → Properties → Digital Signatures. Should show "Microsoft Corporation".
- Resource Usage:: Idle CPU near 1-5% and memory under 100 MB is normal; consistently high resource use from the service is suspicious.
- Behavior:: Skype-service should run as part of Skype; a standalone background service without a Skype UI may indicate tampering.
