Device Cards:
- Previously released to WIP channels June 2025, the ‘Device info’ Card on the Settings Home page has been refined based on early learnings. This update simplifies key device specifications and improves consistency across the end to end flow from the Home Card to the Settings > System > About page, making information easier to scan and understand. This consumer experience is currently rolling out to Insiders in the United States.
- A version of the Device info Card intended for enterprise users on IT managed devices continues to be available.

In Settings > System > About, based on early customer feedback, key device hardware details are once again prominently displayed at the top of the page, making it easy to understand your device at a glance. The Device information section now brings together additional system details such as graphics and storage information in a single location, with easy copy/paste support to simplify sharing or support scenarios. Device related frequently asked questions are not currently surfaced as we continue iterating the best way to deliver contextual help across Settings.

Improved the reliability of sending larger files using nearby sharing.

Paint App update rolling out

With Paint version 11.2601.391.0, we’re excited to introduce freeform rotate, a highly requested feature that gives you more control when editing your artwork. You can now rotate shapes, text, and any active selection to any angle. To get started, open Paint and select a shape, text, or selection. When the object is active, use the rotate handle above it to rotate freely in any direction. For more precise control, you can also choose Custom rotate from the Rotate menu and enter a specific angle. Try using freeform rotate in your artwork to adjust elements exactly the way you want and add more flexibility to your creative workflow.
