In Windows 10, you can broadcast your WiFi, Ethernet, or cellular data connection as a Wi-Fi hotspot. This allows other devices to connect to it. This can be done through the Settings app. Follow these steps to create a WiFi Hotspot on your PC or laptop.
Step 1 Open Settings. Press the start button and then the settings gear on the lower-left hand side of the menu.
Step 2 Click the “Network & Internet” section on main Settings screen.
Step 3 Select “Mobile hotspot” in the list from the left pane.
Step 4 Select which connection you want to share under “Share my Internet connection from”. Press the “Edit” button to change the hotspot’s name and password as you prefer. If you want to automatically turn on the hotspot if both devices (PC and that device) are Bluetooth-enabled, you can choose “Turn on remotely” option.
Step 5 Toggle on the slider radio button. Other devices will now see your hotspot and connect to it.
You can customize “Battery Saver” under Start > Settings > System > Battery Saver. It comes online automatically when the charge drops below 20%.
