I'm using windows xp and I'm looking for a feature that is available in almost all linux window managers, which is to be able to give focus to a window when the mouse hovers over it (without selecting it by clicking on it).

I know adding 1 to HKEY_CURRENT_USER\Control Panel\Desktop\UserPreferencesMask almost does the trick, however I'm not pleased with the result: when the mouse hovers over a window, the task bar changes from the previous application to the one where the mouse is hovering over, and the previous application's border fade out, while the one over which the mouse is gets its borders bluer, including the top blue bar with the minimize, maximize and closing buttons. I find it very aggressive to my eyes (for example, if you move your mouse quickly from left to right, while having two applications on each side of the screen, you would see borders flashing everywhere. Try it you'll see, it's annoying and it gets your attention off of the window's content). Linux doesn't do that.

So in other words, I was wondering if it's possible to give a window focus without having the graphical/visual effects (that is, one the one hand, the task bar that gets darker on the currently focused window, and on the other hand, the border and the top bar that gets more blue when it's focused) associated with it.

check in the area of control panel > system > advanced tab> performance Settings button > visual effects tab. You can manually manipulate many of the visual effects in that section. – Phillip R. Jun 9 '12 at 1:04
I knew about this section, and after rereading it, I don't see any option that would solve my issue – kbell Jun 9 '12 at 1:30
Might not be able to be done if it is not in that section. – Phillip R. Jun 9 '12 at 1:44
