KB5087545: Overview with user sentiment and feedback

Overview

KB5087545 is the May 2026 cumulative update for Windows Server 2022, released as part of Microsoft's regular monthly patching cycle. This update addresses security vulnerabilities and system stability improvements across Windows Server 2022 installations. The patch has been documented to affect systems with specific language pack configurations, particularly those with Polish (pl-PL) language packs installed.

General Purpose

• Delivers monthly security patches and bug fixes for Windows Server 2022
• Includes cumulative updates to system components and drivers
• Addresses component-based servicing (CBS) dependencies and package management
• Targets build 20348.5139.1.14 for affected systems

General Sentiment

Community feedback on KB5087545 is mixed, with reports of installation failures on production systems. While the patch itself represents standard monthly maintenance, users have encountered significant deployment obstacles related to language pack component dependencies. The issue appears isolated to systems with specific language pack configurations, particularly Polish language packs, where orphaned superseded package components cause CBS resolution failures. Microsoft support documentation exists but lacks clear remediation guidance for affected administrators.

Known Issues

• Installation fails with error 0x80073701 (ERROR_SXS_ASSEMBLY_MISSING) on systems with Polish (pl-PL) language packs installed
• CBS engine fails during package pinning when referencing missing Microsoft-Windows-Editions-ServerStandard-Deployment-LanguagePack components from older builds
• Superseded language pack components remain in the component store with missing WinSxS payload directories, blocking update installation
• DISM /CheckHealth and /ScanHealth do not detect the missing component payload, only manifesting as failure during actual update execution
