Default Behavior

Windows Mobile Hotspot Service is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Mobile Hotspot Service is started, it is running as NT Authority\LocalService in a shared process of svchost.exe along with other services. If Windows Mobile Hotspot Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the icssvc service has failed to start due to the error.


Windows Mobile Hotspot Service cannot be started under any conditions, if the following services are disabled, deleted or working improperly:
