KB5061026: Overview with user sentiment and feedback

Overview

KB5061026 is a Security Monthly Quality Rollup released on June 10, 2025, for Windows Server 2008 systems. This update is part of Microsoft's Premium Assurance program for Windows Server 2008, which is approaching its end of support date on January 13, 2026. The update follows previous security updates KB5058449 and KB5061198 (both released on May 13, 2025) and contains various security improvements to internal Windows OS functionality.This monthly rollup is available for both x86-based and x64-based Windows Server 2008 systems, with file sizes of approximately 163.7 MB and 242.6 MB respectively. As Windows Server 2008 is in its final months of extended support through the Premium Assurance program, this update represents one of the last security patches that will be available for this legacy server operating system before its complete end of life in January 2026.It's important to note that this update requires users to have the latest Servicing Stack Update (SSU) KB5056457 installed before it can be applied. Without the latest SSU, the update will not be offered to devices, potentially leaving systems vulnerable to security risks if not properly updated.

General Purpose

The primary purpose of KB5061026 is to address security vulnerabilities in Windows Server 2008 systems. The update specifically focuses on miscellaneous security improvements to internal Windows OS functionality, helping to protect these legacy server systems from potential threats during their final months of extended support.This update is part of Microsoft's June 2025 Security Updates, which address various security concerns across Microsoft products. While the specific details of the security vulnerabilities addressed are not explicitly mentioned in the available information, they are likely documented in Microsoft's Security Update Guide for June 2025. The update builds upon previous security patches from May 2025 (KB5058449 and KB5061198), suggesting it continues to address ongoing security maintenance for this aging server platform.As Windows Server 2008 approaches its final end of support date in January 2026, these monthly security rollups are critical for organizations that still rely on this legacy server operating system and have purchased the Premium Assurance extension. The update helps these organizations maintain security compliance and protection against newly discovered vulnerabilities while they complete their migration plans to more modern Windows Server versions.

General Sentiment

The general sentiment surrounding KB5061026 appears to be neutral to cautious. As this is a security update for a very old operating system that is approaching its final end of support, there is limited discussion about it in the broader community. Most organizations have likely already migrated away from Windows Server 2008, as its standard Extended Security Updates (ESU) ended on January 10, 2023, and the Azure-only ESU support ended on January 9, 2024.For those still using Windows Server 2008 under the Premium Assurance program, there may be some concern about the known issue where the update might fail to install with the error message "Failure to configure Windows updates. Reverting Changes. Do not turn off your computer." This can occur if the system is running an unsupported edition or doesn't have an ESU MAK add-on key properly installed and activated.The requirement to install the latest Servicing Stack Update (SSU) before applying this patch adds another layer of complexity to the update process, which might frustrate administrators of legacy systems. However, this is standard procedure for Windows updates in recent years, especially for older operating systems.Overall, while the update itself appears to be straightforward in addressing security concerns, the context of managing an end-of-life server operating system likely contributes to a cautious sentiment among the limited number of IT professionals still maintaining these systems.

Known Issues

• After installing this update and restarting the device, users might receive the error "Failure to configure Windows updates. Reverting Changes. Do not turn off your computer", and the update might show as Failed in Update History. This issue is expected if installing the update on a device running an edition not supported for ESU. The issue may also occur if users do not have an ESU MAK add-on key installed and activated.* If users have an ESU key and encounter this issue, they should verify they have applied all prerequisites and that their key is activated.
