IMPORTANT　Some customers who use Windows Server 2008 SP2 and have activated their ESU multiple activation key (MAK) add-on before installing the January 14, 2020 updates might need to re-activate their key.　Re-activation on the affected devices should only be required once.  For information on activation, see this blog post.

IMPORTANT　WSUS scan cab files will continue to be available for Windows Server 2008 SP2.　If you have a subset of devices running these operating systems without ESU, they might show as　non-compliant in your patch management and compliance toolsets.

IMPORTANT　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.

IMPORTANT　Starting on January 15, 2020, a full-screen notification will appear that describes the risk of continuing to use Windows 7 Service Pack 1 after it reaches end of support on January 14, 2020. The notification will remain on the screen until you interact with it. This notification will only appear on the following　editions of Windows 7 Service Pack 1:

Note　The notification will not appear on domain-joined machines or machines in kiosk mode.

• Starter.

• Home Basic.

• Home Premium.

• Professional. If you have purchased the Extended Security Update (ESU), the notification　will not appear. For more information, see How to get Extended Security Updates for eligible Windows devices and Lifecycle FAQ-Extended Security Updates.

IMPORTANT Starting in August, 2019, updates to .NET Framework 4.6 and above, for Windows Server 2008 SP1, Windows Server 2008 R2 SP1, and Windows 7SP1, require SHA-2 Code signing support. Please make sure that you have all the latest Windows Updates before applying this update to avoid installation issues.

IMPORTANT All updates for .NET Framework 4.7.2, 4.7.1, 4.7, 4.6.2, 4.6.1, and 4.6 require that the d3dcompiler_47.dll update is installed.
