Known issues in this update

Symptom Workaround
Windows devices using more than one (1) monitor may experience issues with desktop icons moving unexpectedly between monitors or other icon alignment issues when trying to use Copilot in Windows (in preliminary version).

To prevent users from experiencing this issue, Copilot in Windows (in preview) may not be available on devices that have been used or are currently used in a multi-monitor setup.

We are working on a resolution and will provide an update in a future release.

Copilot on Windows (in preview) is currently not supported when your taskbar is located vertically on the right or left of your screen.

To access Copilot on Windows, make sure your taskbar is positioned horizontally at the top or bottom of your screen.

We are working on a resolution and will provide an update in a future release.

After installing KB5034203 (dated 01/23/2024) or later updates, some Windows devices that use DHCP option 235 to discover Microsoft Connected Cache (MCC) nodes in their network may not be able to ‘use these nodes. Instead, these Windows devices will download updates and applications from the public Internet. IT administrators are also seeing an increase in download traffic on their Internet routes.

Those of you using Windows Home Edition probably won’t encounter this problem. MCC and DHCP Option 235 are typically used in enterprise environments.

Option 1: Configure the Microsoft Connected Cache endpoint in the DOCacheHost policy as specified in the cache hostname. Additionally, DOCacheHostSource must be set to 1 or removed as shown 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 assistance from Support for business.

We are working on a resolution and will provide an update in a future release

After installing this update, you may not be able to change the profile picture of your user account.

When you try to change a profile photo by selecting the Start button > Settings > Account > Your information and, under Create your photo, clicking Find one, you might receive an error message with error code 0x80070520.

We are working on a resolution and will provide an update in a future release.
