KB5055609: Overview with user sentiment and feedback

Overview

KB5055609 is an April 2025 Monthly Rollup update for Windows Server 2008. This cumulative security update contains improvements and addresses security vulnerabilities. The update is particularly notable as it comes near the end of the Extended Security Update (ESU) support period for Windows Server 2008, which will end in January 2026.

General Purpose

This update implements important security improvements including enhanced protections for certificate authority vulnerabilities and changes to system folder security. A key change involves the creation of a new %systemdrive%inetpub folder as part of security enhancements. The update also addresses Kerberos Authentication vulnerabilities related to certificate authorities in the Windows root store but not in the NTAuth store, which may result in Event ID 45 logs on domain controllers.

General Sentiment

The sentiment around this update appears cautious but necessary. While it implements important security improvements, there are some potential installation issues to be aware of. The update requires specific prerequisites including having the latest Servicing Stack Update (SSU) installed. Some users may experience installation failures if they don't meet all requirements or don't have proper ESU licensing in place.

Known Issues

• Users may receive the error "Failure to configure Windows updates. Reverting Changes" after installation and restart
• The update may show as Failed in Update History
• Installation issues may occur if the device is running an edition not supported for ESU
• Problems may arise if an ESU MAK add-on key is not properly installed and activated
