ReactOS 0.4.16 serves ’90s Windows nostalgia with fewer bugs

ReactOS has released version 0.4.16, which includes a unified boot and live CD image, a graphical installer, and significant upgrades to video, audio, networking, and storage stacks. The update addresses compatibility issues with legacy software, particularly with video drivers and the kernel’s system page table entries, improving stability. A new HD audio bus driver has replaced an older implementation, and the UniATA driver has been replaced with a new ATA driver for better compatibility and boot times. Networking capabilities have improved with expanded support for adapters and asynchronous connections. A headless Server Core installation type has been introduced, and compatibility restrictions with Windows Server 2003 have been lifted. ReactOS remains in an alpha state, and version 0.4.16 is available for download.

Windows Search still can’t find half my files, because Microsoft fixed the wrong part

Windows 11's native Search feature has been improved with a new indexing system that automatically indexes frequently accessed folders. The latest build, 26100.9267, allows search results to appear after two keystrokes and is more forgiving of typographical errors. Users can choose between web or store suggestions. However, issues persist, such as files remaining invisible in indexed folders. Users have two indexing options: Classic mode, which covers limited locations, and Enhanced mode, which indexes all partitions but may affect battery life and CPU usage. Many users prefer third-party alternatives like Everything, which indexes files directly from the NTFS Master File Table without requiring mode selection. Despite improvements, the overall search experience in Windows remains unsatisfactory.

The 32-year-old Windows placeholder that Microsoft says is now a permanent feature

The Windows Format dialog box was initially created in late 1994 by Microsoft engineer Dave W. Plummer as a temporary solution during the transition from Windows 95 UI to Windows NT. It has remained largely unchanged for over three decades, retaining many of the same options and layout, despite the advancements in Windows 11's design. The dialog box has effectively functioned over the years, leading to a lack of updates or complaints from users. Additionally, the FAT32 format limit of 32GB, also established by Plummer, persisted until it was raised to 2TB in 2024, although the maximum file size remains at 4GB. Windows 11 features many elements from older versions, including the Windows 7 personalization menu and the Disk Management utility, showcasing a blend of nostalgia and functionality.

Windows 11 Search is fixing its biggest annoyance, will find files in folders you actually use

Windows 11 Search is a crucial tool for users who create and download files, but it often struggles to find recently accessed files due to its indexing limitations. Microsoft is introducing a feature called “Automatically find additional relevant locations,” which will automatically identify and index folders based on user activity, reducing the need for manual indexing. Currently, Windows Search maintains an index focused on specific folders, which can lead to frustrations when files are not found. Users can manually add locations or switch to Enhanced mode for broader indexing, though this may result in irrelevant search results and increased resource usage. The new feature aims to streamline the search process by making significant folders searchable automatically while allowing users to block any unwanted folders. Additionally, Microsoft is enhancing Windows Search to better recognize typos and plans to disable Bing search and ads in results. These updates are expected to be rolled out later this year.

The 200GB catch hiding in Windows 11’s new recovery feature

Microsoft has introduced point-in-time restore for Windows 11 users, enhancing the traditional System Restore. This new recovery tool allows users to recover their PCs from software issues, problematic drivers, or faulty updates, even when Windows won’t boot. It uses the Volume Shadow Copy Service (VSS) to automatically generate restore points every 24 hours, which include both system and user files, unlike System Restore. Point-in-time restore manages storage by deleting restore points after 72 hours and integrates seamlessly into Windows Settings, being activated by default for volumes over 200GB. Users with smaller volumes must activate it manually. It also incorporates Reserved Storage to ensure restore points do not consume regular disk space. The feature is available on Windows 11 Home and Pro editions with the installation of the optional Preview Update KB5095093. Users can access point-in-time restore through Windows Settings under System > Recovery, and initiate recovery via the Windows Recovery Environment (Windows RE).
Running pgvector in production on Amazon Aurora PostgreSQL

Running pgvector in production on Amazon Aurora PostgreSQL

Running pgvector on Amazon Aurora PostgreSQL-Compatible Edition offers a vector store with operational capabilities, high availability, and scalability. It is favored for Retrieval Augmented Generation (RAG) workloads transitioning to production, but increased traffic introduces challenges like query latency and memory management. Key operational practices for pgvector workloads include selecting the appropriate index type (HNSW or IVFFlat), establishing a baseline schema, choosing a suitable distance operator, scaling the index through quantization and partitioning, and preparing for churn and observability. The prerequisites for using pgvector include an Aurora PostgreSQL-Compatible cluster with specific PostgreSQL versions and the vector extension enabled. The embedding model used in examples is Amazon Titan Text Embeddings V2, which produces 1024-dimensional embeddings. pgvector supports two Approximate Nearest Neighbor (ANN) index types: HNSW, which is efficient for querying and allows for incremental insertions, and IVFFlat, which is less resource-intensive but requires rebuilding if data changes. There are scenarios where forgoing an index is beneficial, such as small datasets or partitioned datasets requiring 100% recall. A baseline schema for a multi-tenant document store includes creating a table for documents with an embedding vector and establishing indexes for tenant IDs and embeddings using HNSW. The recommended parameters for HNSW include m = 16 and ef_construction = 128. Scaling to millions of vectors involves quantization, tuning HNSW parameters, and partitioning. Aurora Optimized Reads can extend effective cache capacity, and managing index churn is crucial for maintaining performance. Observability metrics include query-level statistics, instance-level metrics, and custom application-defined metrics. To clean up after testing, it is advisable to drop the created indexes and tables, and delete the Aurora PostgreSQL-Compatible cluster and any manual snapshots taken during testing.

GigaWiper: Anatomy of a destructive backdoor assembled from multiple malware

Microsoft Threat Intelligence has identified the GigaWiper malware, which has been detected in compromised environments since October 2025. This malware has destructive capabilities and comes in two forms: standalone wiper binaries and larger binaries with backdoor functionalities, both developed in Golang. The standalone wiper operates at the physical disk level, overwriting disk content and removing partition references. The backdoor variant includes the same wiper functionality and adds persistence through a registry key and scheduled tasks, along with command and control communication via RabbitMQ and Redis. GigaWiper can execute various commands, including wiping drives, triggering a Blue Screen of Death (BSOD), file encryption that mimics ransomware behavior, and managing system elements. The malware integrates components from multiple malware families, including wipers and ransomware mechanisms, and has been linked to a previous malware known as FlockWiper. To defend against GigaWiper, organizations are advised to implement security measures such as tamper protection, blocking access to known C2 infrastructure, and utilizing endpoint detection and response solutions. Microsoft Defender provides detections for GigaWiper and related malware, and threat intelligence reports are available for customers to stay informed about threats. Indicators of compromise include specific SHA-256 hashes and IP addresses associated with GigaWiper.
