It's Not Your Desktop
Everyone seems to be annoyed and confused about the (Metro) interface. It is not your desktop - it is your START screen. Easily enter your Desktop by selecting its Icon on the Start screen or press the Windows Logo key and the letter D.
If there are frequently used apps on the Start screen that you want on your Desktop then simply Pin them to the Task Bar.
My opinion: If you can't cope with Windows 8 - DON'T - get your inner child an Etch-a-Sketch.
