Quote:Microsoft has just confirmed a Windows Update issue that affects the company's Windows 11 operating system. Some users may experience issues installing the most recent security update for the operating system.

Microsoft released the security update on February 13, 2024 as part of its February 2024 Patch Day. The update, which has the ID KB5034765, is the most recent cumulative update for Windows 11 at the time of writing. It is offered for devices running Windows 11 version 22H2 and 23H2.

The update fixed 41 unique security issues in both operating system versions. Two of the issues are rated critical, which is the highest rating available. Apart from security fixes, the update moved the Copilot for Windows icon to the right side of the taskbar. The feature is rolling out gradually to all devices with the security update installed.

Microsoft did not list any known issues at the time for the update. The issue happens if the update is downloaded through Windows Update and also if it is downloaded manually. Deleting downloaded Windows Update files does not resolve it.
