How to set up a Hotspot or Soft AP on Windows 10?
Starting with the Anniversary Update, Windows 10 users with mobile PCs and devices can quickly and easily enable mobile hotspot functionality, allowing you to share your Internet connection with up to 8 other devices.

Choose the connection to share your Internet
