title: How to remove windows.h calls from application?
body: <p>I have an application that uses windows.h but I am tasked with removing the calls to Windows functions.</p>
  
  <p>I am using Visual Studio Express 2010 and when I delete the <code>#include "windows.h"</code> line the code is still able to compile and I can right click and "Go To Definition" for all the variables associate with the windows include file.</p>
  
  <p>I removed <code>$(WindowsSdkDir)include;</code> from the VC++ Directories in the Configuration Properties page but that didn't seem to make a difference. I believed that could be the case because windows.h can be found at <code>C:\Program Files (x86)\Microsoft SDKs\Windows\v7.0A\include\windows.h</code> on my computer.</p>
  
  <p>How do I completely break this link so Visual Studio can give me errors for all calls to that library?</p>
