As a reminder to advanced IT administrators, updates to .NET Framework 3.5 for Windows 8.1 and Windows Server 2012 R2 should be applied only on systems on which .NET Framework 3.5 is present and enabled. Customers who try to pre-install updates to .NET Framework 3.5 to offline images in which the .NET Framework 3.5 product is not enabled will expose these systems to failures to enable .NET Framework 3.5 after the systems are online. For more extensive information about how to deploy .NET Framework 3.5, see Microsoft .NET Framework 3.5 Deployment Considerations.
