I have become tired of reading about how to enable Wifi HotSpot in Windows 10 . The reference is here: https://msdn.microsoft.com/en-us/library/windows/desktop/dd815243%28v=vs.85%29.aspx?f=255&MSPPError=-2147217396 . ( also, for bandwidth throttling you can try  https://github.com/jagt/clumsy and / or https://reqrypt.org/windivert.html   )

I was trying to make a Windows Store application – but, apparently, it is very difficult to run command lines application from Windows Store/

So I made a small powershell file ( hosted at https://github.com/ignatandrei/WIFIHotSpot )
