Downgrade to WinXP and you will have no problems.

siealex,
There is a much easier solution: disable UAC. But it is a bad solution.

@ghisler(Author): maybe it's possible to register window as IDropTarget and _also_ with DragAcceptFiles function? Maybe this could allow to drop at least normal files for elevated TC?

That doesn't seem to work: I called DragAcceptFiles(handle,true) for TC itself and for its file panels, but the cursor remained "forbidden" when dragging from lower to higher level instance. I can drag files from elevated to TC to non-elevated already in older versions, though.

Mhmm, besides DragAcceptFiles, have you also called DragDropInit? (from www.ghisler.ch/board/viewtopic.php?t=34523)

Yes I have.

So it seems that there is definitely no way to drag objects from non-elevated Explorer to elevated TC :-/

And that is fine because it would be a security risk.
It was one of the better ideas from Microsoft to prevent this.

Yes, you are right, this would be a security hole.
