WLAN AutoConfig (Wlansvc) Service Defaults in Windows 10

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 10 it is starting only if the user, an application or another service starts it. When the WLAN AutoConfig service is started, it is running as LocalSystem in its own process of svchost.exe. If WLAN AutoConfig fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Wlansvc service has failed to start due to the error.

Dependencies

WLAN AutoConfig cannot be started under any conditions, if the following services are disabled, deleted or working improperly:

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:
