Extensible Authentication Protocol - Windows 7 Service

The Extensible Authentication Protocol (EAP) service provides network authentication in such scenarios as 802.1x wired and wireless, VPN, and Network Access Protection (NAP). EAP also provides application programming interfaces (APIs) that are used by network access clients, including wireless and VPN clients, during the authentication process. If you disable this service, your computer is prevented from accessing networks that require EAP authentication.

This service also exists in Windows 10, 11, 8, Vista and XP.
