1. Cortana (the new Digital Assistant) can help you with many tasks - like locating and tracking a package your bought and seeing where it is now.
2. Start Menu is easy to use and features both Apps and Tiles for each navigation.
3. Settings is a new digital format for Control Panel (from Windows 7 and 8) and you can customize your Windows 10 experience easily through the Settings options.
Will keep you all posted as the book nears completion.
