Known issues in this update

Symptom	Workaround
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).	To prevent users from encountering this issue, Copilot in Windows (in preview) might not be available on devices that have been used or are currently being used in a multimonitor configuration. We are working on a resolution and will provide an update in an upcoming release.
Copilot in Windows (in preview) is not currently supported when your taskbar is located vertically on the right or left of your screen.	To access Copilot in Windows, make sure your taskbar is positioned horizontally on the top or bottom of your screen. We are working on a resolution and will provide an update in an upcoming release.
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.	Option 1: Configure Microsoft Connected Cache endpoint in DOCacheHost policy as indicated in Cache hostname. Additionally, DOCacheHostSourcehas to be set to 1or removed as indicated in Cache hostname source. By default, the DOCacheHost and DOCacheHostSource policies have no value. Option 2: You can mitigate this issue using Group Policies available through our support channel. Organizations can request help at Support for business. We are working on a resolution and will provide an update in an upcoming release.
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.	We are working on a resolution and will provide an update in an upcoming release.
