WinAutoHotspot
Autoruns Mobile Hotspot from Windows's Anniversary Update after the login
It's crazy hack in every way. First, it checks the internet connection and then it opens Mobile Hotspot settings and presses 6 times TAB and SPACE. This is the way how it enables the Mobile hotspot... It's really crazy but there is no other way how to do it better now
How to install or uninstall the app
You have to download the repository and run install.bat or unistall.bat. Then it will start the hotspot automatically after login. But you should configure Mobile hotspot somehow.
