WLAN AutoConfig (WlanSvc) Service Defaults in Windows 8

The WLANSVC service provides the logic required to configure, discover, connect to, and disconnect from a wireless local area network (WLAN) as defined by IEEE 802.11 standards. It also contains the logic to turn your computer into a software access point so that other devices or computers can connect to your computer wirelessly using a WLAN adapter that can support this. Stopping or disabling the WLANSVC service will make all WLAN adapters on your computer inaccessible from the Windows networking UI. It is strongly recommended that you have the WLANSVC service running if your computer has a WLAN adapter.

Default Behavior

WLAN AutoConfig is a Win32 service. In Windows 8 it will not be started until the user starts it. When the WLAN AutoConfig service is started, it runs as LocalSystem in a process of svchost.exe, sharing it with other services. If WLAN AutoConfig fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the WlanSvc service hasn't been started.

WLAN AutoConfig can't start, if any service from the list below is disabled or not available:
