Microsoft rolls out fix for broken Windows Start Menu search

Microsoft has implemented a server-side remedy for an issue affecting the Windows Start Menu search functionality on select Windows 11 23H2 devices, which began impacting users on April 6. The problem was linked to a server-side Bing update aimed at improving search performance. Microsoft has rolled back the problematic Bing update and expects search issues to decrease as the fix is deployed. Users have reported blank search results in the Start Menu, but options remain clickable. Microsoft confirmed that the issue will resolve automatically with the rollout of the fix, provided devices are connected to the internet and Web Search is enabled.

Microsoft confirms Windows 11 dark mode upgrade, with plans for third-party apps and Registry Editor

Windows 11 has introduced a dark theme that has received positive feedback, but certain legacy pop-ups, like the Properties tab, still use a light background. Microsoft is working on a dark-themed Properties tab and aims to enhance the dark mode experience across the operating system, as confirmed by senior executive Marcus Ash. He mentioned that there are no specific timelines for updates to legacy tools like the Registry Editor, but improvements are being made for consistency in dark mode across system-level dialogs. Third-party applications that do not adopt dark mode will continue to display in light mode, as Microsoft cannot enforce changes on them. Users currently experience inconsistencies with dark mode, particularly with legacy features that still show a light background. In December 2025, Microsoft rolled out dark mode for most operational dialogs, including those for file deletion and error notifications. Dark mode is now visible in various pop-ups, such as notifications for insufficient disk space and Recycle Bin confirmations. Microsoft is also testing dark mode in Windows Run (legacy).

PoC Published for Microsoft Windows Flaw That Allows Low-Privileged Users to Force Irrecoverable BSODs

Security researchers have developed a working Proof of Concept (PoC) exploit for a vulnerability in the Windows kernel, identified as CVE-2026-2636, which allows low-privileged users to induce a Blue Screen of Death (BSoD), resulting in a Denial of Service. This vulnerability is linked to the Windows Common Log File System (CLFS) driver, specifically the CLFS.sys component, and arises from improper handling of invalid or special elements within CLFS (CWE-159). The PoC demonstrates that a non-administrative user can trigger the bug by executing a crafted ReadFile operation on a handle linked to an opened .blf log file without the expected I/O Request Packet (IRP) flags set. This leads to a critical inconsistency in the driver, causing Windows to invoke the kernel routine KeBugCheckEx, which results in a BSoD. The CVE-2026-2636 has a CVSS score of 5.5 (Medium) and poses a high impact on availability, allowing any authenticated user to crash the host reliably. Microsoft addressed this vulnerability in the September 2025 cumulative update, protecting systems running Windows 11 2024 LTSC and Windows Server 2025 by default. However, older or unpatched builds remain vulnerable. Organizations are advised to verify the deployment of the September 2025 updates, prioritize patching multi-user systems, and monitor for unusual spikes in BSoD events.

How to Disable Copilot in Windows 11 — Uninstall, Hide, and Stop It from Coming Back

Microsoft has integrated its AI assistant, Copilot, into various parts of Windows 11, including the taskbar, Edge, and Notepad. Users have expressed a desire to remove Copilot, leading to the creation of a guide detailing methods to disable it. Copilot can be uninstalled through Settings, but additional steps are required to remove it from Edge, Notepad, and Windows Search. Users can also prevent Copilot from reinstalling after updates by adjusting registry settings. The Copilot app is categorized as a standalone application in Windows 11 24H2, making it easier to uninstall compared to previous versions. Methods to disable Copilot include: 1. Uninstalling the app via Settings. 2. Hiding the icon from the taskbar. 3. Using Group Policy Editor (limited to Pro, Enterprise, Education). 4. Removing Copilot for all users using PowerShell. 5. Adjusting settings in Edge and Notepad to disable Copilot features. 6. Editing the registry to remove Copilot from Windows Search and Paint. 7. Remapping the physical Copilot key on newer laptops. 8. Disabling silent reinstallation of Copilot through registry edits. Disabling Copilot will not affect core Windows functionality but will remove AI-specific features such as the chatbot and writing assistance.

Opinion: Windows 11 isn’t the disaster some claim – and it’s time to say so

Windows 11 has faced challenges, including a comprehensive list of top issues identified in 2025, but it is not uniquely unstable compared to earlier versions like Windows 95, 98, XP, 7, and 10. Recent headlines have highlighted various problems such as printer malfunctions and performance issues, but these are often exaggerated due to increased visibility. Historically, Windows has experienced similar cycles of instability, and the perception of widespread failure today is amplified by rapid documentation of minor issues. User trust in Windows has eroded, with skepticism about performance stemming from cumulative updates and the personal impact of issues on over a billion users. The focus should shift to improving predictability and transparency regarding updates rather than solely counting bugs. Windows 11's frequency of out-of-band updates is comparable to that of Windows 7 and 10, with improved mechanisms for addressing problems quickly. Gamers continue to adopt Windows 11 due to enhanced CPU scheduling, improved GPU performance, and features like Auto HDR and DirectStorage. Microsoft is committed to further improving the gaming experience. The scale of Windows operations, with over a billion users and multiple concurrent releases, contributes to occasional anomalies. Despite criticisms, most Windows 11 systems operate without significant issues, performing adequately for daily tasks and gaming. Microsoft has announced plans for enhancements, including bug fixes, performance improvements, and security upgrades, indicating that Windows 11 remains a solid choice for users.
