New Copilot+ PC Experiences
Recall Homepage
- A new personalized homepage in Recall makes it easier and faster to find and reconnect with the apps and websites that matter most to you.
- After opting into snapshot collection, the homepage will:
- Display your most recent Recall snapshots for quick resumption of previous tasks.
- Show the top 3 applications and websites you've spent the most time on in the past 24 hours.
- You can filter which apps, websites, and content types are saved in snapshots for privacy.
Navigation Bar in Recall
- There’s now a left-side navigation bar for faster access to Home, Timeline, Feedback, and Settings within Recall.
New Settings and Features (with toggle enabled)
Move On-screen Hardware Indicators
- You can now move hardware indicators (like brightness, volume, airplane mode, and virtual desktops) to different positions: bottom, top left, or top center.
- Find this new option in Settings > System > Notifications > Position of the onscreen pop-up.
Start Menu Changes
- Admins can set Start Menu pins to apply once, after which users can customize their own layout safely. (Via Start Pins policy and CSP.)
File Explorer
- AI actions in File Explorer are being re-rolled out. These may have temporarily disappeared for some Insiders.
Settings
