Following our announcement from last week, we have now released the fix through Windows Update for the issue with Windows Server 2012 R2 Update communicating with WSUS 3.2 servers in certain non-default configurations. For servers that have already installed the update, Windows Update will re-offer the complete update, but it will only install the fix. Please read KB2959977 and the WSUS team blog for further details.
As always, we’ve been listening to your feedback and want to ensure that you have a smooth deployment experience and continue to receive enterprise-grade protection. As a result, we have extended the timeframe for you to deploy the update. You now have until the August “update Tuesday” to apply this update to your Windows Server 2012 R2 servers. This provides a four-month window to deploy the update as appropriate to your organization. Any security updates during this four-month window can be applied to servers without requiring the full update to be installed.
More information can be found on the Windows Springboard blog.
