KB5039211: This security update includes quality improvements.

Bug Fixes

• This update addresses security issues for your Windows operating system.

Known Issues

• Windows devices using more than one (1) monitor might experience issues with desktop icons moving unexpectedly between monitors or other icon alignment issues when attempting to use Copilot in Windows (in preview).
• Copilot in Windows (in preview) is not currently supported when your taskbar is located vertically on the right or left of your screen.
• After you install KB5034203 (dated 01/23/2024) or later updates, some Windows devices that use the DHCP Option 235 to discover Microsoft Connected Cache (MCC) nodes in their network might be unable to use those nodes. Instead, these Windows devices will download updates and apps from the public internet. IT administrators also see increased download traffic on their internet routes.

Those of you who use the Home edition of Windows are not likely to experience this issue. MCC and DHCP Option 235 are typically used in enterprise environments.

• After installing this update, you might be unable to change your user account profile picture.

When attempting to change a profile picture by selecting the button Start> Settings > Account > Your info and, under Create your picture, clicking on Browse for one, you might receive an error message with error code 0x80070520.
