Microsoft has released the May optional update for Windows 11 version 24H2, introducing features such as the Win + C keyboard shortcut for quick access to Copilot, a drag tray feature, and cross-device resume notifications for OneDrive files.

New text actions for summarizing, creating bulleted lists, or rewriting highlighted text are available for AMD and Intel-powered Copilot+ PCs. Pen users can configure a shortcut button for Click to Do, and Windows Search improvements allow direct typing of settings. The Narrator feature provides detailed descriptions of images for blind and low-vision users. Energy saver controls for IT admins have been introduced, along with HDR and Dolby Vision controls. A new FAQs section in Settings assists users with common inquiries, and mouse settings have been simplified. Users can now edit images shared through the Windows Share window, and a new drag tray area appears when dragging local files. Taskbar policies have been improved to allow unpinning specific apps.

Microsoft May Patch Tuesday fails on some Windows 11 VMs

Microsoft's recent Patch Tuesday update for Windows 11 has faced significant issues, particularly affecting users on versions 22H2 and 23H2. The installation of the May 13 update is failing on some machines, especially in virtual environments, leading to recovery mode entries and boot errors. Users are advised to avoid the update temporarily. The error message indicates a problem with the ACPI.sys file, which is crucial for managing hardware resources. Windows 11 Home and Pro users are likely unaffected, as virtual machines are typically used in enterprise settings. Microsoft has not provided the number of impacted users or a workaround beyond uninstalling the patches, but engineers are working on a resolution. This incident follows previous patching challenges faced by Microsoft this year, including an emergency update for Windows 10 and issues with Remote Desktop sessions in earlier updates.

Signal now blocks Microsoft Recall screenshots on Windows 11

Signal has introduced a "screen security" feature in its Windows application to enhance user privacy by preventing Microsoft's AI-driven Recall functionality from capturing content displayed within the app. This feature is active by default on all Windows 11 devices and sets a Digital Rights Management (DRM) flag on Signal's app windows. Recall, launched in May 2024, captures screenshots of active windows and has raised privacy concerns, leading Microsoft to make it optional and implement various security enhancements. Users can disable Signal's screen security but will be warned about potential privacy risks. Signal's developer, Joshua Lund, highlighted ongoing concerns regarding privacy in applications like Signal and called for a balance between privacy and accessibility in AI technologies.

Windows Remote Desktop Gateway UAF Vulnerability Allows Remote Code Execution

A critical vulnerability, designated as CVE-2025-21297, has been identified in Microsoft’s Remote Desktop Gateway (RD Gateway) due to a use-after-free (UAF) bug linked to concurrent socket connections during the service's initialization. This flaw, located in the aaedge.dll library within the CTsgMsgServer::GetCTsgMsgServerInstance function, allows multiple threads to overwrite a global pointer, leading to potential arbitrary code execution. The vulnerability affects multiple versions of Windows Server, including 2016, 2019, 2022, and 2025. Microsoft released security updates in May 2025 to address the issue, implementing mutex-based synchronization.

Windows 10 PCs are locking and crashing after May’s security update

Microsoft's KB5058379 update has caused issues for Windows 10 users, prompting unexpected requests for the BitLocker recovery key during startup.
