Overview

KB5099552 is a Safe OS Dynamic Update for Windows Server 2022 released on July 14, 2026, targeting improvements to the Windows Recovery Environment (WinRE). This update addresses critical compatibility issues introduced in the June 2026 security update and refines hotkey handling behavior. The update is non-mandatory and does not require system restart after installation.

General Purpose

• Enhances Windows Recovery Environment (WinRE) functionality and stability
• Resolves OLE Automation compatibility issue (oleaut32.dll) affecting COM method invocations with BYREF parameters
• Corrects parameter ownership management for applications using IDispatch::Invoke methods
• Refines hotkey unregister and cleanup behavior for improved keyboard shortcut handling
• Replaces previous update KB5094157 with improved implementation

General Sentiment

This update addresses a legitimate compatibility regression introduced by the June 2026 security update, making it a necessary corrective release. The OLE Automation fix targets a specific technical issue that could impact legacy applications relying on COM interoperability. While the hotkey behavior change is noted as affecting rare cases, the straightforward resolution through application restart and the non-disruptive installation process (no reboot required) position this as a low-risk maintenance update.
