I have a problem with Intel HD Graphics 530 drivers for Windows 7 which integrated in Intel(R) Core(TM) i3-6100 CPU @ 3.70GHz. i've tried to install driver ver 15.60, 15.45, 15.40 with 6Gen CPU capability from https://downloadcenter.intel.com/ Drivers & Software , but nothing changes. Driver don't works. Max resolution 1366*768. OS cannot calculate Windows Experience Index. DirectX tests unavailable.
When you say "Driver don't works" do you mean that installation failed?
Visit https://downloadcenter.intel.com/product/88345/Intel-HD-Graphics-530 Downloads for Intel® HD Graphics 530 again.
Select OS from right pull-down menu (you tried a 15.60 driver, that is Windows 10 exlusive)
Hit "show more".
To bypass message "best driver is already installed", "customized computer manufacturer driver" or "computer is not validated" install driver via have disk method as described at:

Actually, the recommended drivers for Skylake are 15.45. The latest available version for Windows 7 x64 is 18.104.22.16860. This is what I am running on my Skylake-equipped Intel NUC systems.
Hope this helps,
