Overview

KB5095051 is a cumulative security update for Windows 11 version 26H1 released on June 9, 2026 (OS Build 28000.2269). This patch delivers the latest security fixes and quality improvements, including updates from prior optional preview releases. It applies to all editions of Windows 11 version 26H1 and includes updates to AI components alongside standard security and reliability enhancements.

General Purpose

  • Security Updates: Addresses June 2026 security vulnerabilities with comprehensive security fixes
  • BitLocker Reliability: Improves BitLocker Drive Encryption testing by ensuring all required USB BIOS logo test files are available
  • Folder Customization Security: Introduces security hardening for desktop.ini file processing to enhance system protection
  • AI Component Updates: Updates Image Search, Content Extraction, Semantic Analysis, and Settings Model components (applicable to Copilot+ PCs only)
  • Servicing Stack Update: Includes KB5101277 to improve Windows update installation reliability and robustness

General Sentiment

This update represents a standard monthly security release with generally positive improvements to system reliability and security posture. However, the patch introduces two confirmed known issues affecting user workflows: one impacting third-party application integration with Microsoft Office, and another displaying incorrect file names in Recycle Bin deletion dialogs. While these are documented and workarounds exist, they warrant attention before deployment in production environments.

Known Issues

  • Microsoft Office applications might fail to open from certain third-party apps (CCH Engagement, Workpaper Manager, Dentrix, Softdent, Zotero, and similar applications using OLE automation)
  • Deleting from Recycle Bin displays internal file name instead of original file name in confirmation dialog (resolved in KB5095091)
