After looking into it more it's just a chipset driver. Windows is recommending it, so I installed it and have no issues, no real performance improvement either.
On another forum someone thought it might be in preparation for Windows 10.
Either way If you get it in your updates, go ahead and install it.
This now is also in windows 7 I haw no trust no more because one windows 8.1 udate for tablet atom procesor update caused to stop work for all input devices.
