Windows 11 26H1: Microsoft’s driver changes target platform, WLAN, storage, and GPU debugging

Microsoft has refreshed its driver documentation for Windows 11 version 26H1, focusing on enhancements within the driver ecosystem rather than user-centric features. The Windows Driver Kit 10.0.28000.1839, released on May 4, 2026, is designated for driver development on this version and supports Visual Studio 2026. Networking drivers have been updated to support WPA3 Compatibility Mode Security, with an upgraded WiFiCx TLV parser and the removal of outdated WDI datapath definitions. The storage driver stack now accommodates SD Ultra Capacity (SDUC) for cards exceeding 2 TB and up to 128 TB. In graphics, kernel header definitions for GPU Process Debug Blob Collection have been introduced, and static analysis integration has been intensified with updated CodeQL suites. These updates aim to prepare the driver base for future hardware demands and improve driver quality and compatibility.

Microsoft solves case of vanishing Windows 11 desktop — fix is rolling out for blank desktop, taskbar freezes and other flakiness

Windows 11 has been experiencing interface issues, including a freezing taskbar, unresponsive File Explorer, and blank desktops, which Microsoft has categorized as 'general reliability' issues. To address these concerns, Microsoft is rolling out the May update for Windows 11, which began distribution last week. This update aims to enhance the reliability of components like explorer.exe, taskbar menus, and Task View interactions. Users may experience improvements in performance, particularly during sign-in processes and when managing items in File Explorer's Quick Access. The update is also being tested for the upcoming 26H1 version for Arm-based Snapdragon devices. Despite the positive changes, some users remain cautious about potential new glitches.

CVE-2026-45585: YellowKey BitLocker Bypass

BitLocker, a security feature for data protection, has a vulnerability identified as CVE-2026-45585, also known as YellowKey, which allows unauthorized access to encrypted data on Windows 11 versions 24H2, 25H2, 26H1, and Windows Server 2025. This flaw does not compromise BitLocker’s encryption but affects the recovery environment supporting it. The vulnerability can be exploited locally through the Windows Recovery Environment (WinRE) by an attacker with physical access, who can trigger an unrestricted shell and access the BitLocker-protected volume. Microsoft has provided two mitigation strategies: modifying the WinRE image to remove the autofstx.exe entry and transitioning from TPM-only protection to a TPM+PIN requirement at startup. The exploit poses challenges for detection, as it occurs pre-boot and currently lacks vendor-published indicators of compromise. Organizations using BitLocker for unattended devices are particularly at risk, as the vulnerability can lead to loss of confidentiality if an attacker gains access before the legitimate user.

Windows is entering its “Agentic Era”—and its AI architect is moving on

Yusuf Mehdi, head of product marketing for AI and Copilot at Microsoft, is transitioning to a new role focused on reimagining Windows before leaving the company after 35 years. He aims to enhance Microsoft 365 services and the vision of One Copilot in the upcoming fiscal year. In late 2022, Pavan Davuluri initiated a reorganization to develop an agentic operating system, consolidating engineering and features teams for better cohesion. Microsoft plans to introduce a new agentic workspace feature with AI agents in secure sessions, allowing users control over data sharing. The company has moderated its AI integration strategy in Windows 11 to improve user sentiment and is addressing pain points through the Windows K2 project, which will continue through 2026. Jacob Andreou has been appointed as the lead for consumer and commercial Copilot experiences, reporting to CEO Satya Nadella. Mehdi expressed gratitude for his time at Microsoft and reassured his team of a smooth transition.

Microsoft’s PowerToys is getting a low memory mode that kills idle utilities hogging Windows 11 RAM

Microsoft PowerToys is introducing a new optional low memory mode to address significant memory usage from inactive background processes. This feature, developed by an independent contributor, will close the helper process of specific utilities when not in use, allowing users to relaunch them with a hotkey, albeit with a slightly slower initial launch. The initial rollout will support four tools: Text Extractor, Color Picker, Advanced Paste, and Peek. A shared settings map and helper APIs have been introduced to facilitate this feature, which was renamed to “Close apps when inactive” during the code review process. Users can enable this memory-saving behavior globally or for specific applications, with each supported module featuring a toggle on its settings page. The feature is not yet available in PowerToys, and the default behavior will keep background processes running until users opt into the new feature. The code has passed initial validation checks and is awaiting final confirmation before public release.

Microsoft says public sharing of Windows 11 vulnerability violates ‘best practices’

A security researcher known as Nightmare-Eclipse revealed a vulnerability in Windows 11, named YellowKey, which allows attackers to access BitLocker-encrypted drives through the Windows Recovery Environment. Microsoft acknowledged the vulnerability, assigned it the identifier CVE-2026-45585, and criticized the public sharing of its proof of concept. Currently, there is no patch available for the BitLocker bypass, but physical access to the device provides some protection. The vulnerability does not exist in Windows 10 due to differences in the Windows Recovery Environment. The attack requires a stolen Windows 11 laptop and a USB stick, and the vulnerable filesystems include NTFS, FAT32, and exFAT. Nightmare-Eclipse speculated that the bypass may function as a backdoor, while Microsoft referred to it as a "security feature bypass vulnerability."
