No windows.h file

That is indeed a known bug in the new software. There is a workaround for it listed somewhere on the microsoft website. Couldn't find it quickly, the work around was that you had to edit a file manually and after that restart the environment.

Thanks, i'll have a search for it.

Here is the bug workaround, just incase someone else is looking for it:

Hello and thank you for your bug report. Unfortunately this issue was a late regression before Beta 2 released. The workaround is provided in the Known Issues document: "C++ Directories can be added, removed or changed by modifying the VCProjectEngine.dll.express.config file located in the .\vc\vcpackages subdirectory of the Visual C++ Express Edition install location in a text editor, saving the changes and restarting the Visual C++ Express Edition." Please let us know if this does not resolve the problem for you. Thank you, April Reagan, Visual C++ Program Management
