Gradual rollout

Start Menu

Microsoft has made changes to the new account manager in the Start menu, bringing the Sign Out button back into the foreground, which should make it easier to sign out. Switching to another profile still requires opening the extra "..." menu.

Taskbar

Microsoft is introducing the ability to share local files directly from taskbar search results.

Settings

The Settings > Windows Update > Advanced options > Delivery Optimization page has been updated to match the Windows 11 style.

Lock screen

Media controls now appear at the bottom of the lock screen when playing media.

Share dialog

This update removes the search field from the Share dialog.

Features available right away

IE mode

Fixed an issue where Microsoft Edge would occasionally stop responding when using Internet Explorer mode.

Protection of personal data

Fixed an issue where a PIN was required every time an encrypted email was opened in Outlook or other encrypted email applications.

Copilot Pro Subscription

You can now manage your Copilot Pro subscription from the Settings app under Accounts. You must be signed in to a Microsoft account.

Task Manager

Fixed an issue where Task Manager would become unresponsive when switching from a high-contrast theme to a normal theme.

Transmission Control Protocol (TCP)

Fixed an issue where there was a discrepancy in data between TCP_INFO_v1 and GetPerTcpConnectionEstats . The tools used to analyze TCP connection performance are used by file synchronization services. The issue negatively impacted the accuracy of these tools.

Country and Operator Settings Asset

Updated Country and Operator Settings Asset (COSA) profiles for some mobile operators.

Microsoft Defender for Endpoint

Fixed an issue where Work Folders would not sync if Defender for Endpoint was enabled.
