if you wanna use the last SDK, but own only the express version you can do it this way:

Run as Administrator

C:\Windows\System32\cmd.exe /E:ON /V:ON /T:0E /K "C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin\SetEnv.cmd" /Release

copy paste:

WindowsSdkVer.exe -version:v7.0

done!

To switch back for any reasons use

WindowsSdkVer.exe -version:v6.0A
