Windows 11: May patches are being distributed. Among the novelties, the new Xbox mode

The usual Patch Tuesday appointment with Microsoft brings a series of innovations that go well beyond simple security maintenance. The cumulative updates identified by the codes KB5089549 (for versions 24H2 and 25H2) and KB5087420 (for 23H2) introduce long-awaited functional changes, starting with storage volume management.

There are several significant updates in this patch, one of which concerns the longstanding 32GB limit for formatting FAT32 volumes from the command line, now officially raised to 2TB. This was a technical constraint that persisted for decades, limiting user flexibility in cross-platform compatibility scenarios. For the consumer side, the standout feature is the integration of Xbox mode directly on the desktop. This function allows users to transform the PC experience into something very similar to what is seen on the Redmond consoles, optimizing the interface for navigation with a controller and reducing the impact of background processes during gaming sessions. It is a decisive step towards unifying ecosystems, appealing to handheld console owners and those using the computer connected to the TV in the living room.

Windows 11: May 2026 Patch Tuesday focuses on gaming and productivity.

The refinements have also deeply affected File Explorer. The list of natively supported archive formats further expands, now including uu, cpio, xar, and NuGet packages (nupkg). Microsoft has also resolved some longstanding visual annoyances, such as the white flash that appeared when opening "This PC" or resizing the details pane while dark mode is active. The persistence of display and sorting preferences in system folders like Downloads and Documents has also improved.

The update enables new haptic feedback effects for compatible input devices (Surface Slim Pen 2 and some selected models from ASUS and MSI). Users will now be able to feel tactile signals during common operations such as aligning objects in PowerPoint or resizing windows via snapping.

Voice typing has also been streamlined: the new design removes the full-screen overlay to show animations directly on the dictation button of the touch keyboard, reducing visual distractions.

For system administrators, an interesting novelty concerns the security of batch files. Through a new registry key, it is possible to enable a protected processing mode that prevents modification of script files during their execution, mitigating potential runtime tampering attacks.

The May package corrects a total of 120 vulnerabilities, 17 of which are classified as "critical." Fortunately, no zero-day vulnerabilities were actively exploited at the time of release. The focus was on fixing 61 Elevation of Privilege (EoP) flaws and 31 Remote Code Execution (RCE) issues. Particularly relevant are the fixes made to the Windows DNS client and the Native WiFi Miniport driver, which could have allowed remote code execution.

Microsoft has also locked down the Office suite, resolving several bugs related to the handling of malicious files that could be triggered even through the simple preview pane.
