We’ve had a great response to Windows 7 and Windows Server 2008 R2 Service Pack 1 (SP1) through the Microsoft Download Center and Windows Update. Windows 7 SP1 continues to roll out on Windows Update. For customers with IT departments, today we are making SP1 available on the WSUS (Windows Server Update Services) catalog, which makes it available through management tools including WSUS, System Center and others. These tools make it easy for IT professionals to deploy SP1 in their environments in an automated fashion and at their own pace.
