1. Open the Start menu and click on the "Settings" (the gear icon).
2. In the Settings window, click on "Apps."
3. From the left sidebar, select "Default apps."
4. Scroll down and click on "Web browser."
5. A list of installed web browsers will appear. Select "Google Chrome".
6. If Chrome is not listed, click on "Choose a default" and select Chrome from the list of available browsers.
7. Close the Settings window.
Chrome should now be set as the default browser on THE Windows system.
