People tell me that updates are annoying, and slow… but they are for your protection. Windows, Android, iOS, Wii U, Xbox 360, whatever… you should keep them up to date. Sometimes new features emerge, sometimes it is a behind the scenes security enhancement, but you should always install updates, and uninstall them only if necessary.
To keep your Surface tablet updated, you should go to the Start Screen and type “Windows Update” – then, click Settings on the right side, and click on “Install optional updates.” Then search for and apply the latest. If you haven’t done this since buying your Surface RT tablet, it will update your Office 2013 to the full Home and Student edition, along with applying several updates to keep you safe on the internet!
