Installing MATLAB Psychtoolbox on Windows 10

PC spec
Dell Inspiron 13 7000 (2-in-1)
Windows 10 Home 64bit
Core i3-6100U

It was the first time to use a Windows 10 PC for me. So I can't tell what causes this slow processing.... Anyway, I successfully installed Psychtoolbox onto Windows 10 PC with MATLAB 2014b after some struggles.

First I downloaded and installed MATLAB 2015a and Psychtoolbox, but MATLAB crashed when I called Screen function. Then I installed 2014b instead of 2015a, and MATLAB told me to install Gstreamer, which is a familiar comment for me. After installing Gstreamer, the screen function worked. I don't know the reason of the crash first I met.

** P.S.
Psychtoolbox 3 with MATLAB 2015a woked on Windows 10 PC.
