Instructions
Click the Windows "Start" button and type "world of warcraft" in the search text box. Press "Enter." A result window displays the location of your "WoW" installation.
Double-click the "World of Warcraft" directory. Double-click "Interface," then double-click "Addons" to open a list of "WoW" tools. Each tool displayed in the "WoW" interface matches the folder name. Therefore, if you want to delete a tool named "MyMod," you must find the folder named "MyMod."
Right-click the folder you want to uninstall and select "Cut." If you do not want to keep a copy of the tool, click "Delete" instead of "Cut."
Return to the Windows desktop and right-click the desktop. Click "Paste." If you chose to keep a backup, the folder moves from the "WoW" directory to your desktop.
