Introduction

Microsoft has released the KB5055627 update for Windows 11, introducing advanced AI features, significant bug fixes, and performance improvements. This optional preview update is available for users running Windows 11 version 24H2.

Key Features and Enhancements

AI-Powered Features

Recall (Preview):

Recall is an innovative AI feature designed for Copilot+ PCs, which are equipped with Neural Processing Units (NPUs) capable of over 40 TOPS (Tera Operations Per Second). This feature captures snapshots of user activities across applications, websites, and documents, allowing users to retrieve past interactions by describing content in natural language. Access to these snapshots is secured through Windows Hello authentication, ensuring privacy and control. Users can pause or delete snapshots at any time. (support.microsoft.com)

Click to Do (Preview):

This feature enables users to perform context-sensitive actions on selected text or images within Recall snapshots. For instance, users can copy text, open links, or send emails directly from the snapshot interface. Click to Do can be accessed via the Start menu, keyboard shortcuts, or the Snipping Tool, enhancing productivity by reducing the need to switch between applications. (support.microsoft.com)

Semantic Indexing:

Semantic Indexing enhances the search functionality by understanding the context and meaning behind user queries. This allows for more intuitive searches across files, settings, and applications using natural language. The feature is integrated into the Start menu, Windows Search interface, Taskbar Search box, File Explorer, and the Settings app. It also supports searching for photos stored locally or in OneDrive by describing their content.

File Explorer Enhancements:

The update improves the performance of File Explorer, particularly when extracting zipped files. Users can expect a 5-10% increase in extraction speed, especially for large zip files. Additionally, the Home view now presents pivot-based curated content, prioritizing Microsoft 365 files for easier access. (support.microsoft.com)
