Switching VS2010 to use Windows 7.1 SDK

@for /F "tokens=1,2*" %%i in ('reg query "%1\SOFTWARE\Microsoft\Microsoft SDKs\Windows\v7.0A" /v "InstallationFolder"') DO (

In project properties -> Configuration Properties -> General, set Platform Toolkit to WindowsSDK7.1 (or whatever version you want to use). Remember when you do this to select all configurations (release, debug, etc.) and all platforms (win32, x64, etc.) as appropriate. The documentation says you can set this option in the solution properties, but that does not seem to be the case.

Take a look at this page guys. This is going to solve your problems -> Building Applications that Use the Windows SDK
