Although you will still find all the same settings as the version of the app for Windows 10, in this new version, they are grouped with a different logic, and you will find a lot of new settings.
The new Settings also ditches the homepage, and now, the app opens straight into the System section. As you move between sections, instead of listing all the pages in the left navigation pane, the pages are listed on the right side, and at the top, you will notice breadcrumbs letting you know where you are in the app.
Some sections can show hero controls highlighting specific features and frequently used settings that can change as you modify the system configuration.
Also, the related settings now appear at the bottom of the page instead of on the right side. Furthermore, the Settings app can now recommend settings based on your current configuration. So, if you are not using the optimal recommended settings, you will see a notification suggesting using different settings.
