Q: Can I change settings or install other things on it?
A: Absolutely! Feel free to change layouts, settings, or download and install anything you want from the Google Web Store. Nothing you change or add will be seen by anyone else who uses the computer, in fact it will all be deleted once you log out or shut down. But, everything you change or add will be saved in the cloud with your Google account. The next time you use a Chromebook, or anything like it, all those settings and Apps will pop right back up.
