Windows 10 introduced the Mobile Hotspot service:
How to enable it, set the SSID and password programmatically, using PowerShell or Windows API?
Note: I am not talking about the Hosted Network service (i.e. netsh wlan set hostednetwork mode=allow ssid=Name key=Passphrase). The Mobile Hotspot service works even if a network card does not support Hosted Network.
What I have found so far using Process Monitor is that Mobile Hotspot is managed by the icssvc service and SSID and password are stored as binary data under registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\icssvc\Settings\PrivateConnectionSettings.
