Issue: How to fix KB5019509 fails to install in Windows 11?

I am not sure how to install the newest KB5019509 update for Windows 11, as it stops by the end and says that updates have failed. Could you provide me with some solutions to the update failure maybe?

Solved Answer

Most users do not have to do anything much when it comes to continual Windows updates, as long as they are set to be delivered automatically. In those cases, the operating system updates as soon as it it launched or whenever new patches are released. These updates come around on every second Tuesday of every month in a process known as Patch Tuesday.

In some cases, Microsoft releases out-of-band updates on the third week of the month, which is the case with the KB5019509 update, which was set to be released on December 18, 2022 for all computers running Windows 11 version 22H2 (OS build 22621.675). The latter was a major leap between the patches, as it introduced a myriad of new features and improvements.

KB5019509 is yet another important update that introduces the much anticipated Windows Explorer features. Possibly what users were the most excited about was the new File Explorer tabs feature, which allows using one window when managing several different directories or dealing with specific files.

The update also introduced other improvements to the built-in app, including pinning important files for quick access, improvements to OneDrive and how it is displayed, and much more. Unfortunately, some people said that KB5019509 fails to install, resulting either in error code or simple message that says update failed.

This situation is not unique, and update failures already happened with KB5012643, KB5021234, KB5021233, and many others. In these instances the first thing to do is running the built-in troubleshooter, as it can usually pinpoint at issues and possibly resolve them automatically.
