Microsoft enables Hotpatching by default: Windows updates without restarts become a reality

Beginning in May 2026, Microsoft will introduce Hotpatching as a default feature for compatible systems, allowing security updates to be applied without requiring a restart. Hotpatching updates code directly in the memory of running processes, enabling selective updates without interrupting the entire system. It does not replace monthly security updates but alters their activation process on eligible systems, categorized as security updates within the monthly B releases. Eligible systems must be running Windows 11 version 24H2 or newer and possess suitable licenses such as Enterprise, Education, Microsoft 365, or Windows 365. Management of these updates will be facilitated through Windows Autopatch or Microsoft Intune. Microsoft will continue to utilize baseline updates that require a restart, which will alternate with Hotpatch months. Hotpatching aims to reduce the frequency of restarts tied to security updates, particularly benefiting environments where uptime is critical. However, planned restarts will still be necessary, and robust telemetry and maintenance practices will be needed to ensure smooth operation.

Linux gamers didn’t do anything wrong, but they might pay for Windows piracy anyway

Gaming on Linux has advanced significantly due to Valve's Proton compatibility layer and the Steam Deck, allowing most single-player PC games to run on the platform. Data from ProtonDB indicates that nearly every Windows game is now playable on Linux. However, hypervisor-based DRM bypass techniques have emerged, weakening Denuvo's anti-tamper protections and reviving day-zero piracy. Hypervisors operate beneath the operating system, allowing pirates to manipulate Denuvo's validation checks, drastically reducing the time to crack games. This resurgence of piracy poses security risks, as users must disable kernel-level security features, exposing their systems to vulnerabilities. Irdeto, the company behind Denuvo, recognizes the need for updated security measures, but these could complicate the gaming experience for Linux users. Linux's open-source nature complicates enforcing kernel integrity, making effective anti-cheat and DRM systems challenging. Despite these issues, Linux gaming has seen considerable growth, but the threat of hypervisor-based piracy could jeopardize this progress and lead to tighter DRM measures that may reduce Linux compatibility.

No banking apps on your custom ROM? This new initiative could help.

UnifiedAttestation is a new initiative from Europe aimed at creating a free and open-source alternative to Google’s Play Integrity checks, which are essential for banking, financial, and government applications. Many of these applications currently rely on the Play Integrity API, which does not support custom ROMs or alternative Android forks, limiting access for users of these systems. The initiative is backed by smartphone manufacturer Volla and partners like Murena and iodé OS. UnifiedAttestation will be distributed under an Apache 2.0 license, allowing developers to adapt it, with Volla stating that integration requires only a few lines of code. However, the Graphene OS team has expressed concerns about the ethical implications of smartphone manufacturers determining which operating systems can use their applications, advocating for the regulation of the Play Integrity API instead.

Microsoft’s ReFS File System Remains Inaccessible to Windows 11 Users

Microsoft's Resilient File System (ReFS) supports volumes up to 35 petabytes and offers robust data protection through checksums and continuous integrity checks, reducing the risk of data corruption. However, Windows 11 defaults to the NTFS file system, requiring users to use command-line tools to access ReFS features, which may deter average consumers. ReFS is primarily designed for Windows Server environments and has not gained popularity among general users. Testing shows that Windows 11 formats new drives as NTFS, making ReFS less accessible. ReFS can experience performance degradation on single-drive consumer PCs compared to NTFS and lacks features like file system compression, encryption, object IDs, and extended attributes, raising compatibility concerns. Microsoft has introduced the Agent Launchers framework for AI agent registration in Windows, amidst user backlash regarding the evolution of Windows into an "agentic OS." The Windows and Devices segment generated .3 billion in the last fiscal year, remaining flat over three years, while Gaming and LinkedIn generated higher revenues. Users have reported frequent feature changes and declining quality in Windows 11, with Microsoft's Controlled Feature Rollout system causing inconsistencies across devices. ReFS is accessible through the Dev Drive feature in Windows 11, which prioritizes performance over security. Microsoft faces competition from various fronts, including Valve's SteamOS, Apple's upcoming MacBook, and Google's Chrome OS, particularly in the education sector.

How Letta builds production-ready AI agents with Amazon Aurora PostgreSQL

AI agents benefit from persistent memory, enabling them to recall past interactions and maintain context, which enhances customer experience in scenarios like customer service. The Letta Developer Platform allows developers to create stateful agents with advanced context management features. It supports self-hosting within a virtual private cloud and uses Amazon Aurora PostgreSQL for long-term memory storage. Aurora PostgreSQL offers capabilities such as efficient similarity searches with the pgvector extension, sub-second query latency, and dynamic storage scaling. Letta operates as a persistent service, allowing agents to function independently and scale horizontally using Kubernetes. The platform supports multi-tenancy and includes enterprise features for security and monitoring. To set up an Aurora Serverless cluster for Letta, users must create a database on Amazon RDS, configure security group access, and install the pgvector extension. Letta connects to Aurora using a PostgreSQL connection string. After establishing the connection, users can create agents, send messages, and view agent states and conversation histories stored in Aurora. Letta organizes data in 42 tables, including those for agents, messages, and memory blocks. Users can explore the database schema and examine the structure of stored messages and embeddings. Finally, it is recommended to delete the Aurora cluster and associated resources after completing the integration to avoid charges.

New EDR-Redir V2 Blinds Windows Defender on Windows 11 With Fake Program Files

An upgraded release of the EDR-Redir V2 tool has been developed to circumvent Endpoint Detection and Response (EDR) systems by using Windows bind link technology. This version targets the parent directories of EDR installations, such as Program Files, and creates redirection loops that blind security software while keeping legitimate applications intact. Unlike its predecessor, EDR-Redir V2 uses a more complex mechanism that loops subfolders back to themselves, isolating the EDR's path for manipulation without triggering alarms. The tool utilizes the bind link feature from Windows 11 24H2, allowing filesystem namespace redirection without needing kernel privileges. EDR solutions typically secure their subfolders but cannot entirely restrict writes to parent directories. EDR-Redir V2 queries all subfolders in a targeted parent directory and mirrors them in a controlled directory, establishing bidirectional bind links that create loops for normal access by non-EDR software. In a demonstration against Windows Defender, EDR-Redir V2 successfully redirected access to its operational files, making Defender blind to its actual files. This technique highlights vulnerabilities in EDR systems regarding filesystem manipulations at the parent directory level, suggesting that folder-specific safeguards are inadequate. Although there are no widespread reports of exploits using this method, it poses significant concerns for enterprise environments, prompting security teams to monitor bind link usage in critical directories and implement integrity checks on EDR paths.
