I believe part of the problem here is trying to understand exactly what you, (Funkyecat) mean by activates
Your answer here only serves to confuse the matter.

If you prefer the single click option it certainly does have a lot to do with it.
If you are trying to stop the behaviour shown in the example shown here: Single-Click Mode Point to Select - Enable or Disable
Either use Option One, step 2 or Option Two, step 4 to disable the behaviour.
This is the thread Brink gave credit to masfi
for thinking of creating the above tutorial: How to Disable Hover-to-Select with Single-Click Mode?
If that is still not what you are looking for there is more discussion here. With this one you would have to reverse engineer to dis-able: Mouse Hover Makes Window Active - Enable
If what you are trying to do is defeat the highlighting of what you hover or point at you will have to use a different theme than Aero.
If none of my suggestions are even close you the OP will have to be more descriptive in what you mean by activates.
