Preliminary remarks on the update installation
Please note the information on the installation sequence for Windows Server that Microsoft provides in the KB articles. Windows 7 (dropped out of support in January 2020) and Windows 8.1 in January 2023. ESU support ended in January 2024, but Windows 7 systems can be provided with security updates via Embedded Updates. Windows Server 2012/R2 dropped out of support in October 2023 and will only receive updates with an ESU license. If you are still using Windows 8.1, you can install the Server 2012 R2 updates with ESUBypass (see).
Updates for Windows Server 2012 R2
A rollup (for systems with an ESU license) has been released for Windows Server 2012 /R2. The update history for Windows 8.1 and Windows Server 2012 R2 can be found on this Microsoft page.
KB5041828 (Monthly Rollup) for Windows Server 2012 R2
Update KB5041828 (Monthly Rollup for Windows Server 2012 R2) contains improvements and fixes, and eliminates various vulnerabilities that are not specified. It says about the improvements:
- [NetJoinLegacyAccountReuse] Removes this registry key. For more information, see KB5020276.
- [BitLocker (known issue)] A BitLocker recovery screen shows when you start up your device. This occurs after you install the July 9, 2024, update. This issue is more likely to occur if device encryption is on. Go to Settings > Privacy & Security > Device encryption. To unlock your drive, Windows might ask you to enter the recovery key from your Microsoft account.
- [Secure Boot Advanced Targeting (SBAT) and Linux Extensible Firmware Interface (EFI)] This update applies SBAT to systems that run Windows. This stops vulnerable Linux EFI (Shim bootloaders) from running. This SBAT update will not apply to systems that dual-boot Windows and Linux. After the SBAT update is applied, older Linux ISO images might not boot. If this occurs, work with your Linux vendor to get an updated ISO image.
- [Domain Name System (DNS)] This update hardens DNS server security to address CVE-2024-37968. If the configurations of your domains are not up to date, you might get the SERVFAIL error or time out.

The installation of this Enhanced Security Update (ESU) may fail on an Azure Arc-enabled device running Windows Server 2012 R2.
