↑ List of Changes

↑ Phased Rollout

• Recall (Preview):
  • Do you work with many apps, websites and documents, sometimes struggling to remember where you saw something? Recall offers a new way to safely search what you've seen or done on your Copilot+ PC. Using AI capabilities, you can quickly find information and return to any app, website, image or document by describing its content.
    To use Recall, you'll need to consent to saving snapshots (captures of your activity) and set up Windows Hello to verify your presence, ensuring only you can access these snapshots. You can control which snapshots are saved and pause collection anytime.
    Whether working with documents, presentations, video conferences or multitasking, Recall regularly captures snapshots to help you find information later. When you need to find something you've seen or done, open Recall and authenticate with Windows Hello.
    After finding what you need, you can reopen the app/website/document or use Click to Do to perform actions with any image/text in the snapshot.
    Learn more about Recall in Microsoft's documentation.
• Click to Do (Preview):
  • Click to Do lets you perform quick actions with any content on your Copilot+ PC screen, helping complete tasks in real time and switching you to the best app for the job.
    For example, select an image in Click to Do to remove objects (Photos app) or remove backgrounds (Paint).
    Access Click to Do via WIN + <mouse click>, WIN + Q, Snipping Tool menu, or Print Screen. You can also search for it in the taskbar search box.
    Details at Microsoft's site.
  • On Snapdragon Copilot+ PCs, Click to Do includes text smart actions. Use WIN + <mouse click> or WIN + Q to highlight text, then choose options to summarize or rewrite text (more casual/formal). These use Phi Silica, the local small language model (SLM) built into Windows.
  • Swipe left from the screen's right edge to open Click to Do.
  • Enterprise policies for managing Click to Do are available. Learn more here.
• Enhanced Windows Search:
  • On AMD/Intel Copilot+ PCs, finding documents, photos and settings is easier with Enhanced Windows Search, combining semantic models with traditional lexical indexing.
    Whether searching File Explorer, taskbar search or Settings - just type what you're thinking to find it on your PC. No need to remember exact filenames, document content or setting names.
    The 40+ TOPS NPU in Copilot+ PCs enables this even offline.
    

    Details about semantic search on Copilot+ PCs here.

  • On AMD/Intel Copilot+ PCs, searching cloud photos is simplified. Use natural language queries in File Explorer's search box to find cloud photos by describing content (e.g. "European castles" or "summer picnics").
    Cloud photos now appear alongside local images in search results, including exact keyword matches in cloud file text.
    This works with personal OneDrive storage. Requires Microsoft account sign-in and internet connection.

• Narrator:
  • The "Speech Recap" feature lets you track what Narrator has spoken and quickly access this information. Using simple shortcuts, you can follow real-time transcripts and copy Narrator's last spoken content.
• Phone Link:
  • A new "Phone Link" sidebar in Start menu provides quick access to connected smartphone features - calls, SMS, photos and content sharing between PC and phone.
• Widgets:
  • Web developers can now use existing web content to create dynamic, interactive widgets for Windows 11's Widgets panel. Details in Microsoft's documentation.
  • For EEA Insiders:
    • You can now customize the Weather widget on lock screen. Go to Settings → Personalization → Lock screen and click "Customize widget" in Weather widget's additional options. More widget customization coming later.
• File Explorer:
  • The Home page now shows personalized Microsoft 365 content for easy access.
  • Improved text scaling support in File Explorer, Open/Save dialogs, and file copy windows. Configure in Settings → Accessibility → Text size.
  • Better performance when extracting archived files, especially with many small files.
  • Fixed an issue where the address bar might not show the path after opening a directory.
• Settings:
  • On Copilot+ PCs, you can now control which apps Windows suggests actions from. Find this in Settings → Apps → Actions.
• Windows Studio Effects:
  • Auto-framing in Windows Studio Effects now enables automatically when first using camera on supported PCs.
• Start Menu:
  • Fixed an issue where pinned app pages couldn't be switched via touch screen.
  • Fixed an issue where enlarged text size might hide "Sign out" button and additional options in Start menu's account manager.
• Taskbar:
  • Fixed an issue where app icon underlines might remain visible after closing apps.
  • Fixed an issue where after WIN + T, arrow keys worked incorrectly in Arabic/Hebrew systems.
• Desktop Icons:
  • Updated logic for desktop app icons. Packaged apps no longer show accent color backgrounds (e.g. dragging Snipping Tool icon from Start to desktop). Icons are also larger for better visibility.
• Display:
  • Fixed an issue where WIN + P sometimes required pressing twice to switch projection modes.
