Additional apps can be downloaded from the Windows Store.
Windows 8 comes with an antivirus program called ‘Defender’.
As mentioned above, Windows 8 does still have a Desktop similar to Windows 7. To find this, click the Desktop tile. Instead of Icons, the new Start screen has ‘Tiles’. You click these to open your ‘Apps’ (short for Applications). If you can’t find a particular file, do a right mouse click in the space at the bottom of the screen and click All Apps.
