If you will copy and past any addons into this folder (C:\Program Files\World of Warcraft\Interface\AddOns) you will be able to execute them from the character selection menu after logging into WOW.
1) Download addon. Most of them will come in a .zip file that you will have to open and extract the contents to a folder. I would suggest extracting these files to your desktop for easy access.
2) Goto the folder on your desktop that contains the addon files that you extracted from the .zip file and copy all of the contents in this folder. You will know you are copying addon files because when you open the folder that the files where extracted to (on your desktop) you will see a lot of sub folders some examples would be: AllInOneInventory, AlphaMap, AtlasLoot, etc.. You want to copy all of these sub folders!!! Those are the addons and should be copied and placed in your (C:\Program Files\World of Warcraft\Interface\AddOns)folder. Exit out of this folder and proceed to step 3.
3) Start WOW and after typing in your User name and PW you will come to a character selection screen where you can either create a new character or select an existing one. This is the screen where you will enable your addons. Look in the bottom left hand corner of this screen. You should see an addons button. Just select that button and then put a check in the addons that you want to enable. Then select OK and then select your character that you will be playing. After you have logged into your character you should see all kinds of fun stuff to play with, if not just hit the ESC button and look through that menu.
