Note- this is for Windows 7.. this one is for vista "Ghost" UI elements
So it is not a duplicate.. And also the changing the resolution(the accepted answer on that one), didn't fix it for me.
there may be a windows 7 specific answer
Here is a bit of the desktop.
At some point some old bit of GUI appeared and won't go away. Here it is hovering as I write this question.
It just sits there. And as you can no doubt appreciate, it is a nuisance.
I've tried clicking in the bottom left to mimimize all the windows and clicking again to restore but nope. And i've tried opening a window over it but it just won't paint over it. The unwanted bit of GUI stays on top of anything.
I have tried opening task manager, end tasking explorer and starting explorer again, but nope, still there. so besides restarting windows, what can I do?

And I tried the accepted answer here "Ghost" UI elements (and probably some others too) and the accepted answer of changing resolution, and some others I tried there, didn't work
