title: Missing Debug|Any CPU build configuration for projects and defaulting to Debug|x86 on Windows x64
body: <p>I've just recently reinstalled Windows 7 x64 on my box. The installation succeeded, and I've had no issues with the operating system as a whole. I believe there is a configuration issue with either Windows or .NET x64.</p>
  
  <p>Symptoms</p>
  
  <ol>
  <li>The default build configurations for new projects is <em>Debug|x86</em>. <br/>This doesn't feel right. I'm running an x64 OS, and I'm reasonably confident that for the last three versions prior to this the default build config has been <em>Debug|Any CPU</em>.</li>
  <li><em>Any CPU</em> does not exist as a build configuration for projects at all, and I'm reasonably sure it should. To build anything x64 I need to explicitly add an x64 platform for the project.</li>
  </ol>
  
  <p>Am I correct in thinking that <em>Debug|Any CPU</em> is normally the default configuration. If so, what are some possible causes for this not being the case for any new projects created?</p>
