Following the leaked details related to Windows 7 and Windows Server 2008 R2 Build 6.1.7700.0.100122-1900, one question still remains unanswered. Is Build 6.1.7700.0.100122-1900 the first step to Windows 8 and Windows 8 Server, or just part of the development process on the way to Windows 7 Service Pack 1 and Windows Server 2008 SP1. There’s no way of answering this, at least not for the time being, and not with Microsoft keeping mum on the evolution of the Windows client and server. But one thing is certain: Windows 7 Build 6.1.7700.0.100122-1900 is real and a proof that Microsoft is already hard at work on the evolution of Windows.

Clearly superseding the release to manufacturing (RTM) Build of Windows 7 and Windows Server 2008 R2 was 6.1.7600.16385, the actual bits for Build 6.1.7700.0.100122-1900 have not been leaked. Instead, Russian website Wzor only offered information and screenshots of the releases. The latest find from the leak source is a new feature built into Windows Server 2008 R2 Build 6.1.7700.0.100122-1900.

It appears that Windows Server 2008 R2 Build 6.1.7700.0.100122-1900 will bring to the table a new feature for Hyper-V. The hypervisor role in Build 6.1.7700.0.100122-1900 features Dynamic Memory, allowing customers to specify a certain amount of RAM with which a virtual operating system would start, and a maximum amount of system memory that the platform could use.

Dynamic Memory was a feature explored by Microsoft for Hyper-V in a pre-Beta build of Windows Server 2008 R2, but that was not included into the RTM milestone of the operating system. Since Microsoft confirmed no features for either Windows 8 or Windows 7 SP1, it remains to be seen whether Dynamic Memory will make it into Service Pack 1 for the successor of Windows Vista, or if it will be reserved for the next generation of Windows.
