Today again I had the top section of my windows explorer just disappeared and I was not able to close the program using the x at the top right section of the header.
I was able to recover it by resetting the screen resolution and magnification, then later I found this trick that seems to force a screen reset. I was able to move it to my second screen an there is was just fine, so as long as I did not move it back to the surface primary screen it was just dandy.
The Ctrl+Shift+Win+B key sequence will restart your graphics driver.
