I made this simple batch file for those who need to delete their cache folder, and launch WoW.exe automatically.
To use: Place the wow.bat file in your World of Warcraft main directory.
C:\Program Files\World of Warcraft
Next, right-click on wow.bat and go to "Send To"-"Desktop(create shortcut)"
There should now be a shortcut on your desktop called "Shortcut to wow.bat"
To change its name: Right click on "Shortcut to wow.bat" and go to rename. Give it any name you want.
To change its icon: Right click on the shortcut and go to Properties. Go to the Shortcut tab if not already there. Click the Change Icon button. Browse to your World of Warcraft folder again and select wow.exe. Below you will see the WoW icon highlighted. Click Ok. Click Ok again. Voila you have an Icon.
