Uninstalling Path of Exile properly

I wanted to uninstall PoE, so I used the "Add/Remove Programs" button as usual, but it didn't do anything. I then simply removed folders from 'My Documents/My Games' and '\Program Files\Grinding Gear Games\Path of Exile' directories. My question is if the uninstalling is done or there are other files remaining somewhere I should take care of? If so, how to remove the rest?

Thanks.

I copy paste game client from computer to computer without installation. So I guess there is no more stuff to remove than you typed..

I'm not 100% sure, but i think uninstalling POE keeps a few preference files, therefore doesn't totally removes the main folders.
The most important thing is that POE went away from your add/remove progs list successfully, otherwise that would mean something went wrong.

Thanks for the answers! :)
