On periodic basis we release updates for Windows Azure Guest OS. These OS are generally used by cloud services deployment (mainly PaaS).

Windows Azure supports three Guest OS families.

  • The 3.x versions are substantially compatible with Windows Server 2012.
  • The 2.X versions are substantially compatible with Windows Server 2008 R2 or R2 SP1.
  • The 1.X versions are substantially compatible with Windows Server 2008 SP2.
