Following our announcement from last week, we are happy to announce that Windows Server 2012 R2 Update is now generally available through Windows Update. The Windows Server 2012 R2 evaluation experience and has also been updated to the new OS image. The Volume Licensing Service Center will be updated on April 14, 2014 and the new image will be coming to Azure soon.

We encourage you to apply this update to your Windows Server 2012 R2 systems as soon as possible. As a reminder, this becomes the new servicing baseline for Windows Server 2012 R2 systems, so next month's security updates (i.e. May "patch Tuesday") will be dependent on Windows Server 2012 R2 Update being installed.

Windows Server 2012 R2 Update is categorized as "security update" because it includes two new security fixes (as well as all previously-issued fixes since Windows Server 2012 R2 RTM). Separate versions of these security fixes (KB2922229 and KB2936068) are also available for those organizations that aren't yet ready to deploy the full Windows Server 2012 R2 Update.
