title: Converting Windows App written on XP to Windows 7
body: <p>I inherited a huge code base which was written to work on Windows XP. Now we would like to migrate to Windows 7. I do not know what is the proper way to go about this. What is the proper approach to do the above task? I did some googling on differences between XP and Windows 7 but I do not get any proper links which describe how the internals of 7 differ from XP. Any links will be appreciated. </p>
  
  <p>Usually how do S/W developers migrate their code/apps written for one version of OS say Vista to Windows 7?</p>
