Windows 8
Default Description
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, this computer is prevented from accessing networks that require EAP authentication.

Default Description

Additional Information
This service is required for Wireless Networks as well as the following group of services:
- CNG Key Isolation
- Extensible Authentication Protocol
- Wired AutoConfig (not required for Wireless Networks)
- WLAN AutoConfig
WLAN AutoConfig, if set to Manual, will not start automatically if you use a hardware switch (such as those on laptops to turn on and off the wireless network card). If you require wireless connectivity on your computer, keep the listed services above on the default values as well as place WLAN AutoConfig into Automatic. If you do not have a wireless card installed on the system, or do not require authentication on your wired network card, the group of services can safely be disabled.
