AI function enhancement

Recall AI: Automatically records user operations (such as screenshots, document modifications, web browsing) through the local AI model, and supports backtracking along the timeline. For example, users can quickly find and return to any application, website, image or document by describing the content, and find the Excel table that was modified last Wednesday. This function requires NPU support, and the data is encrypted and stored locally. Users can manually clear the history.

Semantic search: Combining traditional indexing and semantic indexing technology, it supports natural language search for documents and pictures, and can run efficiently offline. Instead of remembering file names or precise contents, users can find what they're looking for by typing descriptive words, such as "Sunset Bridge" to find a picture, or "European travel budget" to find related documents. The semantic search function supports Chinese, English, French, German, Japanese and Spanish, covering a variety of document and image formats, including .txt, .pdf, .docx, .jpg, etc.

AI Canvas (Canvas): Added AI generation function in "Snipping Tool", users can smear any shape and automatically convert it into vector graphics, such as converting hand-drawn sketches into standard flow charts.

Voice assistant Copilot enhancement: supports natural language multi-modal interaction, such as "show my schedule for last week in dark mode". Integrating the OpenAI GPT-4o model (requires subscription to Microsoft 365 Copilot), the response speed is increased by 40%.

Performance optimization

Overall performance improvement: It is said that it can improve the performance of the entire machine, including the graphics card, CPU, etc., with a performance improvement of up to 35%.

Dynamic Power Management 2.0: Optimizes background task scheduling for thin and light notebooks, extending battery life by 20% (Microsoft official test data).

Wi-Fi 7 power saving mode: Reduces antenna power consumption when idle and reduces standby power consumption by 30%.

Hardware support extensions

Processor requirements: At least support Intel 8th generation/AMD Zen 2 and above CPU, some 7th generation Core models are added compared to the 23H2 version.

NPU mandatory requirement: The Copilot+ function requires the device to be equipped with an NPU with at least 40 TOPS computing power, such as Qualcomm Snapdragon X Elite and Intel Core Ultra 200V.

Storage optimization: Allow users to choose to install only core functions (reducing 10GB usage), suitable for low-end devices; the system file compression rate is increased by 15%, freeing up more storage space.

Other hardware support: Supports Wi-Fi 7 and 80Gbps USB4 2.0 ports to increase data transfer speed.

User experience improvements
