Disgruntled researcher drops “BlueHammer” Windows zero-day LPE exploit

A security researcher, known as "Nightmare-Eclipse," released proof-of-concept exploit code for a Windows zero-day vulnerability called "BlueHammer," which allows local privilege escalation (LPE). The exploit has been validated by another researcher, Will Dormann, who confirmed it can escalate privileges on Windows systems, allowing non-administrative users to gain SYSTEM-level access. The exploit's reliability varies across different Windows versions, with inconsistent success rates reported. Microsoft has not acknowledged the vulnerability or provided a patch, raising concerns about potential exploitation by threat actors. Users are advised to restrict local user access, monitor for suspicious activity, and enable advanced endpoint protection.

Microsoft Introduces WinApp CLI to Unify Windows App Development Workflows

In January 2026, Microsoft launched the public preview of the WinApp CLI, a command-line tool for Windows application development that is open source and supports various frameworks including .NET, C++, Electron, and Rust. The tool aims to simplify the complexities of Windows development by providing a unified entry point for environment setup, configuration, and packaging. Key features include the winapp init command for environment initialization, the winapp create-debug-identity command for attaching package identities without full MSIX packaging, and automation capabilities for manifests, certificates, and signing processes. The CLI also supports Electron and Node.js scenarios, allowing developers to inject package identity into running Electron processes. The WinApp CLI is currently in public preview, with potential changes before general availability, and an updated version 0.2.0 was released in late February 2026. It can be accessed via WinGet, npm, and as a GitHub project for community contributions.

Tested: Windows 11 now has a second taskbar, and it works surprisingly well

In 2026, Microsoft released PowerToys version 0.98, which includes the new Command Palette Dock feature. This Dock can be pinned to any edge of the screen and displays information such as CPU and memory usage while providing quick access to frequently used commands. Users can enable the Dock through the PowerToys interface without needing to restart their system. The Dock offers customization options, including repositioning, themes, and backgrounds. It integrates live system statistics, a clock, and allows users to pin commands and applications for a tailored workflow. The Command Palette Dock is designed to complement, not replace, the Windows 11 taskbar. Other enhancements in this update include a new Keyboard Manager, performance upgrades for the Command Palette, and improvements to CursorWrap and ZoomIt.

How PostgreSQL on Azure helps modernize legacy databases

Microsoft is enhancing PostgreSQL to establish it as a high-performance, scalable, and enterprise-ready open database platform, addressing the limitations of legacy systems like Oracle. Many Oracle customers face rising licensing costs, performance bottlenecks, and scalability issues, prompting them to consider migration. Apollo Hospitals successfully migrated from Oracle to Azure Database for PostgreSQL, achieving a 60% reduction in operational costs and a threefold improvement in system performance. Microsoft has introduced an AI-assisted migration tool to simplify the transition from Oracle to PostgreSQL, automating the conversion of schemas and application code. Azure Database for PostgreSQL offers high performance, scalability, and security, with features like v6-series compute SKUs and SSD v2 storage. Azure HorizonDB, a new cloud-native PostgreSQL service, supports extreme performance demands and is designed for real-time analytics. Microsoft is committed to enhancing PostgreSQL as an open-source database for enterprise workloads, enabling organizations to innovate and become more agile.

PostgreSQL on Azure supercharged for AI

Over 80% of developers now incorporate AI tools into their workflows. PostgreSQL is preferred by 78.6% of developers engaged in AI and real-time applications. Microsoft has enhanced its PostgreSQL managed services to meet contemporary developer needs, contributing over 500 commits to the open-source project. The Azure Database for PostgreSQL supports both lift-and-shift and new open-source workloads, while the newly introduced Azure HorizonDB is designed for AI-native workloads. Developers can provision PostgreSQL instances directly from Visual Studio Code, and GitHub Copilot assists in writing and optimizing SQL queries. Azure Database for PostgreSQL facilitates integration with Microsoft Foundry for AI applications and supports high-performance similarity search with DiskANN vector indexing. PostgreSQL 18 is now available on Azure, offering enhanced performance and scalability. Nasdaq has modernized its Boardvantage platform using Azure Database for PostgreSQL and Microsoft Foundry to integrate AI for governance tasks. Azure HorizonDB is a fully managed PostgreSQL-compatible service designed for AI-native workloads, currently in private preview.

Using Windows 10? Do This Now to Lower Your Risk of Being Hacked

Support for Windows 10 officially ended last year, and Microsoft recommends users transition to Windows 11 or buy new computers. Users will no longer receive security updates, and any issues encountered will not be supported by Microsoft. Windows Update will indicate that devices are no longer receiving updates, leaving users to manage security vulnerabilities themselves. Microsoft Defender Antivirus will continue to receive updates until October 2028, and users can enroll in Extended Security Updates (ESU) for an additional year of security updates until October 13, 2026, under certain conditions. Windows 11 installations surpassed Windows 10 in June 2025, with Windows 11 at 53.7% and Windows 10 at 42.7%. Users opting to stay on Windows 10 should implement third-party security solutions to mitigate risks from the lack of official updates.
