Microsoft might not breathe a single word on the next iteration of the Windows client and server platforms for the general public, but the company’s silence should not be mistaken for inactivity. While the software giant is keeping down to a minimum leaks on the development of Windows 8 client and Windows 8 Server, the company is indeed hard at work on the successors of Windows 7 and Windows Server 2008 R2. And while the company is keeping mum on Windows 8, it is already developing technical documentation for the US Department of Justice.
