KB5015882, KB5015814 updates break Start menu in Windows 11


The latest two cumulative updates for Windows 11 – KB5015882 and KB5015814 – are causing major issues for some users, according to multiple reports and Microsoft’s own documentation. The latest round of updates could cause the Start menu to disappear as soon as you try to open it, thanks to a bug in the operating system.

The most recent optional update (KB5015882) brought a new functionality for notifications on Windows 11. The update added an option that allows you to receive urgent alerts even when the update assistance feature point is activated. For those who don’t know, Focus Assist is similar to Do Not Disturb and it’s also available on Windows 10.

Another new addition is the ability to update to a newer version of Windows 11 during OOBE itself. This means that you can install feature updates whenever the operating system boots, but it will only work when the device is eligible for the update. Although it looks like a very nice update on paper, users have reported that KB5015882 breaks the Start menu.

The bug also affects the “Windows” key on your keyboard. Fortunately, Microsoft is aware of the reports and the company has quietly acknowledged that a bug in KB5015814 or KB5015882 affects a “small number of devices” where users cannot open Start.

On affected PCs, clicking or selecting the Start button or using the Windows key on your keyboard may have no effect.

Microsoft has already released an emergency server-side update to resolve the faulty Start menu, but it may take up to 24 hours to automatically push to all devices. If the Start button is still not working on your device, make sure to restart the Windows device as it can apply the update to your device faster.
