The new Windows 10 computers have the four major Internet browsers installed: Edge (new to Windows 10, similiar to Internet Explorer but more secure), Internet Explorer, Firefox, and Chrome.
By default, Edge is the default browser. To change it:
1. In Windows 10, click Start button (Windows icon in the lower left hand corner) and go to Settings (the gear icon near the bottom)
2. Click Apps
3. Click Default apps (on the left)
4. In the Web browser section, click Microsoft Edge (or whatever is listed)
5. Choose the browser you'd like to set as default!
