Windows 7: Game in borderless mode is displaced every time i turn it on

Everytime I start playing league of legends, game window is displaced beyond display, I have to use WinSpy everytime to get it to right position, because of other reasons I have to play it in borderless mode

Anyone has any idea how to make it start in right position?
Or in other words, is there something in registry that saves window position? and how do I get to that?

Hi, i am having this same problem, i thought it was due to a recent patch they launch it a couple of weeks ago, but they ignore the problem and i started searching for problems related to the Graphic card, although i think it is their fault.

NOTE: I use Dual Screen, and since i was having problems with this i was using FULL SCREEN option, and when the game launches the rest of my background applications runing maximized go offscreen as well, or a bit to the left the same width the game itself. What program do you use? WinSpy? gonna check it out, but prefer to resolve the problem by the root and not with other programs :S

example 1
example 2

Exactly the same problem although my window is moved a bit futher and up
Ive learned that you can use Task Manager to move window into the right place by selecting the aplication with RMB and clicking on Maximize, but that just replaces WinSpy, you still have to do that everytime.
Its extremely annoying, but whats even more annoying is that noone knows how to fix it...

I did in fact noticed i could do that with task manager, but i noticed the window "shows" in the right position, but the mouse only interacts in the coordinates the window was before, wich means (in my chase) that i cannot pan to the right, nor bottom since it is where the window borders where before.
