Refer to http://stackoverflow.com/questions/1356653/multiple-compiling-errors-with-basic-c-application-on-vs2010-beta-1

The solution is:

The problem is that in VS2010 the Global options for include paths has been removed. After some searching, I found that the two files that contained these settings (From my previous install of VS) were in the following directory:

C:\users\username\appdata\local\microsoft\msbuild\v4.0\

The two files are:

Microsoft.Cpp.Win32.user.props
Microsoft.Cpp.x64.users.props
Edit the IncludePath variable

Remove the DDK path, saved the file, and restarted VS2010. This resolved my issue for all new projects.
