Overview

KB5055570 is a security-only update for Windows Server 2008 R2 Premium Assurance released on April 8, 2025. This update is part of Microsoft's ongoing commitment to provide security improvements for supported Windows operating systems. The update addresses security vulnerabilities and includes important system protections.

It's important to note that Windows Server 2008 R2 Premium Assurance will reach end of support on January 13, 2026. Microsoft recommends upgrading to a later version of Windows Server to ensure continued security updates and support.

General Purpose

The primary purpose of this security update is to address security vulnerabilities in Windows Server 2008 R2. A key security improvement involves changes to the system that create a new %systemdrive%inetpub folder on the device. This folder is essential for system security and should not be deleted, regardless of whether Internet Information Services (IIS) is enabled. This change enhances system protection and requires no action from IT administrators or end users. The update specifically addresses CVE-2025-21204, demonstrating Microsoft's commitment to maintaining system security even for systems approaching end of support.

General Sentiment

The general sentiment towards this update appears cautiously positive. While the update introduces important security improvements, there are some implementation considerations. The update requires installation of the latest Servicing Stack Update (SSU) KB5056456 before it can be installed, which adds an extra step to the deployment process. Additionally, users working with language packs should install them before applying this update to avoid potential complications. The update's focus on security improvements without reported issues suggests it should be relatively straightforward to implement, though proper preparation is essential.
