Microsoft today released Service Pack 1 for Windows 7 and Windows 2008 R2, to all users. A Service Pack is a periodical cumulative of updates released between a period of time, that also introduces new features to the OS. For both operating systems based on the Windows 6.1 kernel, Service Pack 1 will provide all product and security updates released to date. A couple of new features that will benefit Windows 2008 R2 are also bundled. These include Dynamic Memory and RemoteFX. Dynamic Memory lets Hyper-V administrators pool available memory on a physical host and dynamically distribute it to any virtual machine(s) running on that host, while RemoteFX lets Windows Server 2008 R2 administrators provide a rich end user desktop virtualization experience by delivering vivid content, independent of any graphics stack, to server-hosted virtual and session-based desktops. We put Windows 7 Service Pack 1 to test, to see how the updated OS benefits gamers, or if it does in the first place. Our performance analysis can be read here.
