Sure. But I would like to be able to implement this feature, so I choose
not to use the CreateDesktop() API.

Well - this may be possbible. But it sounds a bit complicated.
The approach to hide windows using SW_HIDE or move them somewhere
abroad into non-visibility is simple and effective.

Well, my implementation also works already (if you don't count a few
bugs that are included), so I will leave it this way.
