Fluid Dictation and Studio Effects: Smarter, Faster, and More Private
One standout feature is fluid dictation, integrated into voice access on Copilot+ PCs. It uses on-device small language models (SLMs) to correct grammar and punctuation in real time. This means fewer manual edits and faster content creation. Importantly, it ensures privacy by processing data locally rather than in the cloud. You can enable or disable it easily via voice commands or settings. Additionally, Windows Studio Effects now supports more cameras beyond integrated laptop ones. This enhancement lets you apply AI-powered video improvements to USB webcams or rear laptop cameras. Such flexibility helps remote workers and content creators look their best across various setups without extra hardware.Improved File Management and Performance Fixes for Seamless Workflows
File Explorer Home introduces on-hover actions, enabling quick file management with commands like “Open file location” and “Ask Copilot about this file.” This streamlines multitasking and boosts efficiency, especially when juggling multiple projects. Microsoft also addressed lag issues affecting File Explorer, taskbar, and browsers. These fixes reduce delays and improve responsiveness, essential for professionals handling resource-intensive tasks. Though some minor bugs remain, the update’s overall stability gains are a significant win.“Performance improvements like these are crucial for developers who rely on Windows as their daily work platform,” noted accessibility advocate Amanda Langowski.
