Announcing Windows 11 Insider Preview Build 26120.3291 (Dev and Beta Channels)

Windows 11 Insider Preview Build 26120.3291 (KB5052080) has been released for the Dev and Beta Channels, introducing enhancements for Snapdragon-powered Copilot+ PCs. Key updates include an improved Windows Search feature that allows users to find cloud-stored files directly from the taskbar search box and a refined Recall (Preview) experience, which will delete previous snapshots but continue saving new ones if enabled in Settings. For Beta Channel users, the same updates are available as optional upgrades, with plans to make them recommended later this year. Insiders can switch from the Dev to the Beta Channel while both channels share identical build numbers, but this option will close once the Dev Channel progresses to higher build numbers. The improved Windows Search feature supports finding cloud-stored photos by describing them, available for users signed into OneDrive with a personal Microsoft account. Support for third-party cloud providers is expected soon. The update also includes fixes for live captions, File Explorer reliability, and issues with Remote Desktop. Known issues include inaccuracies in build version display after a PC reset and problems with Recall not saving snapshots automatically. An update to the Snipping Tool introduces a new trim feature for screen recordings, allowing users to adjust start and end times.

Self-managed multi-tenant vector search with Amazon Aurora PostgreSQL

Organizations are using generative AI and machine learning tools to extract value from unstructured data, employing specialized machine learning models to convert data into vectors for efficient searching and retrieval. Amazon Aurora PostgreSQL-Compatible Edition, with the pgvector extension, allows developers to create a vector store for generative AI applications. Multi-tenant architectures in software-as-a-service (SaaS) applications ensure tenant data isolation to maintain security and privacy. In a multi-tenant scenario, home survey requests are processed, and survey reports are stored in Amazon S3. Embedding models convert these documents into vector embeddings, which are stored in a vector store. There are two approaches to building a vector-based application: a self-managed approach, where developers handle data processing and queries, and a fully-managed option using Amazon Bedrock Knowledge Bases. The self-managed approach involves coding to process data, generate vector embeddings, and store them in Aurora. The architecture includes data ingestion via AWS Lambda, embedding conversion, SQL queries for data retrieval, and response enhancement using a large language model (LLM). Key terminologies include vector embeddings, embedding models, chunking, pgvector, HNSW index, and IVFFlat index. The process of creating a vector store involves configuring the Aurora PostgreSQL database, enabling the pgvector extension, and establishing a schema for the vector store. The vector table includes fields for UUID, vector embeddings, text chunks, metadata, and tenant identification. Data ingestion requires coding to convert data into embeddings and insert them into the database. Retrieval of vector data is crucial for enhancing prompts sent to LLMs, with various distance functions supported for identifying similar vectors. Multi-tenancy is enforced using row-level security in PostgreSQL, ensuring tenant data isolation. The process includes updating query functions to support tenant isolation and setting the current tenant ID for queries.

Microsoft declutters Windows 11 File Explorer for GDPR

Microsoft released the Windows 11 24H2 preview build, 26120.3281, in the Dev and Beta channels, marking the end of the Location History API and addressing European privacy regulations. The Location History feature, which allowed Cortana to access location data for up to 24 hours, has been removed, meaning location data will no longer be saved locally. Microsoft has also disabled account-based content in File Explorer for Entra IDs within the European Economic Area (EEA) to comply with privacy laws, affecting sections like Recent, Favorites, and Recommended content. Additionally, a new feature will allow users to resume OneDrive files from mobile devices to PCs with one click, but an upcoming change will delete all existing snapshots in Recall. There is no timeline for when these updates will be available to the general public.

Simplify database authentication management with the Amazon Aurora PostgreSQL pg_ad_mapping extension

Authentication is essential for security in enterprise environments, protecting sensitive data and resources from unauthorized access. Kerberos authentication is utilized for Amazon Aurora PostgreSQL-Compatible Edition with AWS Directory Service for Microsoft Active Directory, particularly through the pg_ad_mapping extension, which enhances access control management. Aurora PostgreSQL supports multiple authentication methods, including password authentication, AWS Identity and Access Management (IAM) database authentication, and Kerberos authentication. By default, password authentication is enabled, while IAM and Kerberos can be used independently. Users are assigned specific roles based on the authentication method: rds_iam for IAM, rds_ad for Kerberos, and no specific roles for password authentication. Kerberos authentication integrates with Microsoft Active Directory, allowing centralized authentication and single sign-on (SSO) capabilities. With versions 14.10 and 15.5, Aurora PostgreSQL introduced the pg_ad_mapping extension, which allows administrators to manage access through Active Directory (AD) security groups instead of provisioning individual users. This extension checks AD group memberships upon user login and assigns corresponding database roles, prioritizing roles based on assigned weights. The pg_ad_mapping extension includes functions such as pgadmap_set_mapping to add mappings between AD security groups and database roles, pgadmap_read_mapping to list existing mappings, and pgadmap_reset_mapping to delete or reset mappings. To deploy the solution, a CloudFormation stack is used to create necessary resources, including an AWS Managed Microsoft AD server, an Aurora PostgreSQL database cluster, and a Windows EC2 instance. Users can be added to AD groups, and roles can be mapped to facilitate access management. Security best practices for Aurora PostgreSQL include using IAM policies for resource management, implementing security groups for database access control, utilizing encryption for data protection, and employing Transport Layer Security (TLS) for secure connections. For auditing, the pg_stat_gssapi view can be used to identify authenticated users, and enabling the log_connections parameter will log session establishments, including AD user identities.
