Microsoft said that preview OS build 19045.3758 causes problems when using Copilot in multi-monitor configurations. Desktop icons may move unexpectedly across monitors and become misaligned, leading to decreased productivity.

Vole has decided to restrict Copilot access to PCs used in multi-monitor setups before and has also withheld the availability of Windows 11 version 23H2 on such machines.

IT admins have been asked to check against safeguard ID 47615939 in Windows Update for Business reports, to check the compliance status of devices being used across their organisation.

Microsoft has recommended users not manually update to Windows 11 version 23H2 on affected devices through the Media Creation Tool (MCT) or any other mechanism while the compatibility hold is in effect.

Affected client versions of Windows include Windows 11 version 22H2 and 23H2, along with Windows 10 version 23H2. Microsoft has assured users that it is working on a fix that will be offered in an "upcoming release", but no tentative timelines have been offered yet.

This bug is present in a preview build, so there's a chance that it will be resolved before December's Patch Tuesday release.
