Don’t download this if you’re updating just one computer, instead update to SP1 directly by downloading the required updates via Windows Update.If you’ve previously installed a pre-release version of Windows 7 & Windows Server 2008 R2 SP1 on your machine, you must uninstall that version before installing SP1.Any updates for Windows 7 that Microsoft has released since then will not be installed, so you should run Windows Update to install any other available updates.
In order to download and install Windows 7 and Windows Server 2008 R2 SP1 you must currently have a Release to Manufacturing (RTM) version of Windows 7 or Windows Server 2008 R2 already installed. The convenience rollup only contains the updates released after Service Pack 1 and before April 2016.This enables organizations to deploy a single set of updates. It also provides ongoing improvements to the Windows Operating System (OS), by including previous updates delivered over Windows Update as well as continuing incremental updates to the Windows 7 and Windows Server 2008 R2 platforms based on customer and partner feedback. Windows 7 and Windows Server 2008 R2 SP1 helps keep your PCs and servers on the latest support level. The RTM of SP1 is available for Free to everyone but validation is required in order to download it. As promised before, Microsoft has now officially released Service Pack 1 Final (KB976932) for Windows 7 and Windows Server 2008 R2.
