It’s important to understand the current update status and any significant changes that may affect your server environment.
For the most current information regarding known issues that might impact Windows and Windows Server, Microsoft provides a dedicated resource. You can find up-to-date details on the Windows release health dashboard. This dashboard is an essential tool for staying informed about any potential problems and their resolutions.
Key Updates and Important Notices for Windows Server 2012
Several important changes and updates have been implemented for Windows Server 2012 that administrators should be aware of. These include critical security updates and the discontinuation of certain features.
RemoteFX vGPU Feature Disablement
Beginning in July 2020, a significant security vulnerability led to the disabling of the RemoteFX vGPU feature across all Windows Updates. This feature, which allowed for virtualized graphics processing, was removed to mitigate the security risk identified under CVE-2020-1036. Microsoft also provided KB4570006 for further details on this change.
After applying updates from July 2020 onwards, attempts to initiate virtual machines (VMs) with RemoteFX vGPU enabled will fail. Users will encounter error messages indicating that the virtual machine cannot start because RemoteFX-capable GPUs are disabled or due to insufficient GPU resources on the server.
While there is an option to re-enable RemoteFX vGPU, it is strongly discouraged due to the inherent security risks. Microsoft no longer supports the RemoteFX 3D video adapter, and continued use may expose systems to vulnerabilities.
End of Support for Internet Explorer 10
Another crucial update is the end of support for Internet Explorer 10, effective from February 11, 2020. To ensure continued security and access to the latest web technologies, users of Windows Server 2012 are advised to upgrade to Internet Explorer 11. For systems running Windows Server 2012 or Windows 8 Embedded Standard, Internet Explorer 11 can be obtained by referencing KB4492872.
To maintain up-to-date security fixes for Internet Explorer, it is essential to install one of the following updates:
- Cumulative Update for Internet Explorer 11 for Windows Server 2012.
- Cumulative Update for Internet Explorer 11 for Windows 8 Embedded Standard.
- The latest Monthly Rollup update, which includes security updates.
Staying Updated is Key
Regularly updating your Windows Server 2012 to the latest available version is a fundamental practice for robust security and system stability. By applying these updates, you not only gain access to the newest features and improvements but also ensure protection against emerging threats. Make it a routine to check for and install the latest updates to keep your server environment secure and performing optimally.
