As a Monthly Rollup, it contains all security and reliability improvements from previous updates, along with new security patches. Microsoft describes it as containing "miscellaneous security improvements made to internal Windows OS functionality."

The update helps maintain the security posture of these legacy systems while organizations plan their migration to newer Windows Server versions.

General Sentiment

The general sentiment surrounding KB5061059 appears neutral to positive, primarily because there are no documented known issues with this update. This suggests that the update may install smoothly without causing system disruptions.However, there is an important caveat mentioned regarding installation on Azure Arc-enabled devices running Windows Server 2012. The update might fail to install on these systems unless all the required endpoints for ESU are properly configured as described in the Connected Machine agent network requirements.It's worth noting that the limited available information about this update makes it difficult to gauge user experiences or potential undocumented issues. Since Windows Server 2012 is in extended support, the user base is likely shrinking as organizations migrate to newer versions, potentially resulting in fewer reported issues. Organizations still running Windows Server 2012 should carefully test this update in non-production environments before deploying widely, following standard change management practices.

Known Issues
