BigDiskBuster PoC Blocks Windows Defender Updates

A new tool named BigDiskBuster has been released on GitHub, which disrupts Microsoft Defender Antivirus by preventing it from installing updates. It does this by consuming available disk space during the update process, causing Defender to remain on its current version and unable to receive new platform or signature updates. BigDiskBuster operates as a local denial-of-service technique and requires prior access to the target machine to execute. The tool was created by researcher Abdelhamid Naceri, known as Nightmare Eclipse, who has previously worked on similar projects. As of now, there is no CVE identifier, patch, or advisory from Microsoft regarding this issue.

New Windows Defender zero-day blocks Microsoft antivirus updates

Security researcher Abdelhamid Naceri, known as Nightmare Eclipse, released a zero-day exploit called BigDiskBuster that targets Microsoft Defender, preventing antivirus updates and leaving systems vulnerable. BigDiskBuster operates across all supported Windows versions and must run in the background to block updates. Naceri has previously released a similar exploit called UnDefend and has a history of releasing multiple zero-day exploits since April 2026 amid a dispute with Microsoft. Two weeks before BigDiskBuster, he introduced another exploit named ShieldCrash, which grants SYSTEM access and circumvents a patched flaw. Naceri's recent exploits include tools like LegacyHive, BlueHammer, RedSun, YellowKey, GreenPlasma, and MiniPlasma, all targeting Microsoft Defender and other Windows components. Microsoft has warned of potential legal action against malicious activities but has not commented on BigDiskBuster.

Windows 11’s audio bugs won’t be fixed until October

Users of Windows PCs with AMD Radeon GPUs, including models such as RX 6600, RX 7700 XT, RX 7800 XT, RX 7900 GRE, RX 7900 XTX, and RX 9070 XT, may experience persistent issues until October 13th, 2026. These issues include error messages in Device Manager (Code 10), absence of audio output, unresponsive volume controls, inaccessible sound settings, and failures in multi-channel or 3D audio features. Additional problems reported are driver timeouts, black screens, missing displays, and system crashes. Issues with File Explorer and File History have emerged after September's Patch Tuesday updates, affecting the creation and accessibility of backups. Some problems have been resolved through an emergency update, including fixes for Claude Cowork and Remote Desktop Services, and a misleading Defender warning.

Microsoft admits Windows 11’s emergency update still breaks audio, and a fix may not arrive until October

Windows 11 is facing ongoing challenges with audio functionality following recent updates, particularly with the emergency update KB5129195 released on September 14. This update aimed to fix issues from the September Patch Tuesday update (KB5124008) but has led to new problems, including compromised audio output on some devices and disruptions in secure trust relationships for enterprise systems. Users have reported error messages like “This device cannot start (Code 10)” in Device Manager, and issues with USB audio devices. Microsoft is investigating these audio problems but has not provided a timeline for resolution. Additionally, there are reports of GPU issues on AMD systems, including driver timeouts and black screens, affecting various Radeon models such as RX 6600, RX 7700 XT, RX 7800 XT, RX 7900 GRE, RX 7900 XTX, and RX 9070 XT. Some users found that uninstalling the September update alleviated these problems, but the emergency update KB5129195 does not address the GPU errors.

Microsoft is set to revamp the design of outdated dialogue boxes in Windows 11

Microsoft is modernizing the user experience in Windows 11 by redesigning all legacy dialog boxes in response to user feedback. March Rogers, Microsoft's design director, is leading this initiative to ensure consistency across the platform. Specific examples of outdated interfaces include the Speech settings dialog and the Windows recovery menu. Microsoft is using two strategies for updates: incremental updates, which introduce a dark theme across system dialogs, and comprehensive redesigns using the WinUI 3 framework. The Run menu has been completely revamped with a dark theme and improved features, while the previous version remains available for user preference. These updates are currently in test builds of Windows 11. Additionally, Microsoft is rolling out security patches and an emergency patch for issues from the September update.

Do This If You Want Another Year of Windows 10 Security Updates

Microsoft has extended its security update support for Windows 10 until October 12, 2027, through the Extended Security Updates (ESU) program. This extension allows users to maintain essential protection against threats despite the official end of support last year. The ESU program will continue for existing participants without further action required, while new users can enroll until the program concludes next year. To qualify, devices must be running Windows 10 version 22H2 and have the latest updates installed. Enrollment options include purchasing coverage or redeeming Microsoft Rewards points. The program focuses solely on security, providing critical monthly updates without new features.

MuMu Player vs GameLoop vs KOPLAYER: Android 15 Gap

Android emulators for PC have become a crowded market with close to a dozen actively maintained clients. Tencent and NetEase have first-party products like GameLoop and MuMu Player to control the PC on-ramp to their mobile catalogs. Independent players like BlueStacks and LDPlayer focus on platform-agnostic performance and feature breadth. KOPLAYER appears to be abandoned in 2026 with no updates, functioning website, or active development. MuMu Player supports Android 15, offering newer features for mobile games. GameLoop is focused on Tencent's mobile titles with updated documentation. MuMu Player and GameLoop are free, while KOPLAYER is also historically free. MuMu Player and GameLoop have ongoing updates and security, while KOPLAYER's lack of updates poses a security risk.

Gemini’s rough patch with smart home controls has spread to Android Auto

Recent reports indicate that the Gemini smart home control feature in Android Auto has stopped functioning for many users, similar to issues previously experienced by Wear OS users. Despite Google announcing a fix for Wear OS, the cause of the Android Auto malfunction remains unclear. Users have reported that commands for smart home devices, such as turning on air conditioning, are not working, with Gemini providing a message that it "cannot control smart home devices through Google Maps while driving." Some users have reverted to Google Assistant for reliability, as commands still work within the Gemini app. The exact cause of the disruptions is under investigation, with speculation about a potential server-side bug or unannounced changes in functionality. Efforts to obtain a statement from Google are ongoing.

Google’s Android Bench 2.0 tests AI agents on week-long app builds

Google has launched Android Bench 2.0, an upgraded benchmark for evaluating AI coding agents, which now includes 30 long-horizon tasks that can take human engineers days or weeks to complete. The best pass rate for these tasks is around 28%, down from approximately 91% in the previous version. The benchmark measures both pass rates and completion rates, acknowledging partial progress rather than just failures. It assesses various challenges, including app creation and feature integration, using a comprehensive scoring methodology that evaluates functionality, regression checks, and visual fidelity. AI models perform better with new code than with modifications to existing systems, facing challenges in runtime validation and cross-platform conversions. The current leaderboard shows OpenAI’s GPT-6 Astra leading with a 28% pass rate, while Gemini 3.8 Flash has an 8% pass rate. Developers using AI agents should be aware that while AI can generate significant portions of applications, further refinements will require human input. The benchmark is available on Google’s Android Bench leaderboard.
