Microsoft .NET Framework 4.8

REMINDER Windows Embedded 7 Standard and Windows Server 2008 R2 SP1 have reached the end of mainstream support and are now in extended security update (ESU) support.

Starting in July 2020, there will no longer be optional, non-security releases (known as "C" releases) for this operating system. Operating systems in extended support have only cumulative monthly security updates (known as the "B" or Update Tuesday release).

Verify that you have installed the required updates listed in the How to get this update section before installing this update. 

Customers who have purchased the Extended Security Update (ESU) for on-premises versions of these operating systems must follow the procedures in KB4522133 to continue receiving security updates after extended support ends on January 14, 2020. For more information on ESU and which editions are supported, see KB4497181. For more information, see the ESU blog.

The September 12, 2023 update for Windows Embedded 7 Standard and Windows Server 2008 R2 SP1 includes cumulative security and reliability improvements in .NET Framework 4.8. We recommend that you apply this update as part of your regular maintenance routines. Verify that you have installed the required updates listed in the How to get this update section before installing this update.
