Win7 Internet Exporer 11 black vertical bar

Hello everybody,

I have a Win7 64 bit laptop and IE 11.0.9600.16476, when IE is not maximazed the vertical scroll bar doesn't  anchor to the right but is about a centimeter moved to the left, with a black bar on its right.

Moreover since I installed IE11 Windows is less stable, also showing the blue screen, In most cases this happens while using Visual Studio Web Developer 2010 or 2013 using IE.

This is really frustrating, and I'm thinking about switching to IE10 again.

Any suggestions?

Thanks
