Overview

KB5101719 is a Safe OS Dynamic Update released on July 14, 2026, for Windows 11 versions 24H2 and 25H2. This update targets the Windows Recovery Environment (WinRE) with improvements to system stability and compatibility. The update does not require a device restart after installation and cannot be removed once applied to a Windows image.

General Purpose

• Improves Windows Recovery Environment (WinRE) functionality and reliability
• Addresses OLE Automation compatibility issue introduced in June 2026 security update affecting COM method calls with BYREF parameters
• Restores proper parameter ownership management for applications using IDispatch::Invoke method
• Modifies hotkey unregister and cleanup behavior for built-in Windows experiences
• Replaces previously released update KB5095615

General Sentiment

This update addresses critical compatibility issues, particularly for applications relying on OLE Automation functionality. The fix for parameter marshaling errors and automation call failures is significant for enterprise environments. However, users should be aware of a rare edge case where certain built-in Windows experiences may temporarily stop responding to keyboard shortcuts, though restarting the affected application typically resolves this issue.

Known Issues

• In rare cases, some built-in Windows experiences that rely on previous hotkey lifecycle behavior might temporarily stop responding to certain keyboard shortcuts; typically resolved by restarting the affected application.
