Windows BitLocker zero-day gives access to protected drives, PoC released

A cybersecurity researcher known as Chaotic Eclipse has released proof-of-concept exploits for two unpatched vulnerabilities in Microsoft Windows: YellowKey, a BitLocker bypass, and GreenPlasma, a privilege-escalation flaw. The YellowKey vulnerability affects Windows 11 and Windows Server 2022/2025, allowing unauthorized access to BitLocker-protected volumes by exploiting the Windows Recovery Environment. The exploit can be executed using specially crafted 'FsTx' files on a USB drive or directly on the EFI partition. Independent researcher Kevin Beaumont has validated the exploit, which can bypass BitLocker protections even in a Trusted Platform Module (TPM) environment. The GreenPlasma vulnerability allows unprivileged users to create arbitrary memory-section objects, potentially leading to privilege escalation. Chaotic Eclipse has expressed dissatisfaction with Microsoft's handling of bug reports, prompting the public disclosure of these vulnerabilities. Microsoft has stated its commitment to investigating security issues and updating affected devices.

Microsoft aims to speed Windows with ‘leap forward’ in WinUI 3 perf

Microsoft has announced a 25 percent improvement in the performance of WinUI 3, specifically in File Explorer components. There has been a 41 percent reduction in memory allocations and a 45 percent decrease in function calls. Some optimizations may involve breaking changes, which will initially be optional for developers. The enhancements are intended to become the default in future iterations of WinUI and the Windows App SDK. Despite these improvements, developers have expressed concerns about WinUI 3's performance, noting it is slower than WPF and UWP. The reliance on WinRT interop for component actions is seen as a significant factor hindering speed. Additionally, there are historical tensions regarding the adoption of Microsoft's frameworks within the Windows and Office teams, leading to skepticism about their reliability.

Your laptop has a hidden control panel Windows won’t show you

Your laptop's utility application provides various features that enhance productivity, often overlooked during setup. It typically appears on the desktop or taskbar and offers functionalities that extend beyond basic Windows Settings. Key features include: - A dashboard summarizing essential PC attributes such as battery status, memory availability, CPU performance, serial number, and warranty information. - Diagnostic tools for troubleshooting and a method to check for updates, including Windows Update, Microsoft Store, and the utility application itself. - Performance settings for adjusting fan speed, allowing for higher performance or quieter operation. - Options to adjust the color gamut for professionals in photography or design, with different color profiles available. - Charging mode adjustments to extend battery lifespan by limiting charging to around 80% during regular use. - Sound presets to enhance audio quality for music, movies, or gaming. - OLED management features to mitigate burn-in issues on OLED displays. - Presence detection technology that locks the device when the user is away and can utilize facial recognition or smartphone proximity for unlocking.

Android Apps on Windows 11: Safe Alternatives After WSA

In 2025, Microsoft announced it would discontinue support for the Windows Subsystem for Android (WSA), making Android applications non-functional on Windows 11. This decision surprised many users in Indonesia who relied on these applications. HP developed a guide outlining secure alternatives to WSA, which included reputable Android emulators like BlueStacks, LDPlayer, and NoxPlayer, as well as native Windows alternatives such as Microsoft Teams and Microsoft 365 apps. Users were advised against unverified APK sideloading, unofficial emulators, and modified apps due to security risks. Microsoft’s end of support means no further security updates or bug fixes will be provided, and integration with the Amazon Appstore will cease. Users can continue using WSA apps, but they will be exposed to potential security threats. To migrate data from WSA, users were instructed to inventory apps, research alternatives, and export app data before performing a clean uninstall. Best practices for running Android apps safely on Windows included downloading from official sources and keeping software updated.

Windows 11 Adds Feature Flags Page to Insider Program for Enabling Experimental Features Without ViveTool

Microsoft has introduced a new Feature Flags page in the Windows 11 Insider Program, allowing users to toggle experimental features on or off through Windows Settings, without needing third-party tools like ViveTool. This functionality is limited to officially announced features, while hidden or untested features still require ViveTool for activation. The Controlled Feature Rollout system has been phased out, and Insiders in the Beta channel will now receive announced features by default. Users can access the Feature Flags page by navigating through Windows Settings, ensuring their device is set to the Experimental experience, and confirming their operating system version. The Feature Flags page allows users to enable, manage, or disable experimental features, but features not publicly announced will not be listed and will still require ViveTool for activation. The update is available for users in the Windows 11 Insider Program running version 25H2 in the Experimental experience, with no current information on whether it will extend to the Beta channel or stable releases.
