Fixing Lord Of The Rings Online Borderless Windowed Fullscreen

Update 20 March 20120: please refer to this page on PCGamingWiki for further updates on borderless fullscreen windowed mode for any game.

I've been trying to figure out a way to fix the windowed border issue present in games such as Lord Of The Rings Online (LOTRO) in Windows. Usually when trying to run a game in borderless windowed fullscreen, I would set the resolution to the monitor native resolution and  use the program ShiftWindow to coordinate the screen so that the borders would not be visible (guide). However, games like LOTRO forcefully resize the window so that the border is always visible, no matter how you try to manipulate it. So I thought about some other solutions, and hopefully some more intelligent person will help me to figure it out, and in turn, help to fix the same issue in lots of other games too.

Play Any Game In Borderless Windowed Fullscreen (aka Maximized Window)

World of Warcraft and StarCraft II fullscreen side by side, as God intended.

Games like StarCraft II and World of Warcraft provide the option to run their game in "Windowed Fullscreen" (aka Maximized Window). Also modern Valve Source games such as Left 4 Dead, Alien Swarm and Half-Life 2 natively support this mode, calling it "Windowed (No Border)". This is basically a normal windowed game where the window has been stretched to fit the screen in such a way that it looks maximized (by hiding borders of the window and the title bar).

This has several advantages to running a game in traditional fullscreen mode:

1) Ability to alt-tab quickly at any moment, even during loading screens.
2) Does not disturb multi-monitor set ups during loading.
3) Generally more stable experience.
