|Rebooting is simply restarting for a fresh start.|
On Windows 7, you just go to Start, then click on the arrow next to the Shut Down, and select Restart.
On Windows 8, type 'Restart' and the search windows opens up, then click on Settings and you are given the option "Turn Off Your PC" which you then click on. When you click on that, I think I remember that there is an option to restart as well as just a complete shut down, otherwise, let it shut down and then start it again.
You have to be a little bit crazy to keep you from going insane.
