title: OpenGL SDK on Windows
body: <p>I'm trying to write an OpenGL application so I installed the Windows 7 SDK.
  However, it appears that it is OpenGL 1.1...</p>
  
  <pre><code>#define GL_VERSION_1_1                    1
  </code></pre>
  
  <p>How can I find which version of OpenGL I have installed(*.dll) and where can I find the newer *.lib/*.h files?</p>
