Does Windows 7 with platform update support desktop duplication?

Question

The articles in MSDN are misleading and doesn't provide a clear answer whether or not Windows 7 with platform update will support desktop duplication. Did anyone know if this is possible? I am developing an application for desktop streaming, I currently use mirror driver for windows 7, but i am looking for a common solution for windows 7 and windows 8.

I have win8 SDK and VS2010 for development.
