I was trying to find out where to delete oQueue from my world of warcraft, i don't use it, I have windows 7.

Go to the following folder:

World of Warcraft > Interface > Addons

Delete the oQueue folder in there.

Or if you have Icebox you can delete it by finding oQueue in your list of installed addons, check the check box next to its name, and press the uninstall button at the top.
