Issue: How to fix KB5018499 fails to install in Windows 11?

Every time I check my Windows updates, I see that KB5018499 failed to install. After clicking “Retry,” I get the same error every time. Is there a way to get rid of this and install the newest update for Windows 11? I really appreciate any help you can provide.

Solved Answer

The Windows operating system has undergone significant development. With the most recent releases, Microsoft started offering Windows support as a service, which means that users now receive frequent security, feature, cumulative, and other upgrades. They increase the device's stability, enhance already-existing features or add new ones, fix security flaws,[1] distribute the most recent drivers, and more. Updates are unquestionably essential for everyone and shouldn't be ignored.

Usually, pre-set options start the Windows update process automatically, ensuring prompt delivery. Some users prefer to start the process manually, which is another option. Regardless of preferences, there are problems that hinder the deployment of both types of updating methods.

KB5018499 is a routine update released on October 20 as a Preview Build for Windows 11, incorporating builds 22621.870 and 22623.870.

As evident, many users were eager to check these newest improvements, but some have received an error 0x800f0806 when trying to install the latest build (can vary).

Third-party security is known for users' not being able to install the newest Windows updates and may, in some cases, cause errors when trying to do so. This is because, upon installation, security software modifies settings on the kernel[3] level, which may impact how connections to certain servers are handled. In some cases, legitimate connections may be misinterpreted as malicious ones, hence Windows update errors occur. To check if it's the case, you should either temporarily disable protection and attempt to download the newest update or simply uninstall the software.

Protect your online privacy with a VPN client

A VPN is crucial when it comes to user privacy.

Even if you apply the most secure settings via your web browser, you can still be tracked via apps that are connected to the internet. Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds. The best solution for your ultimate privacy is Private Internet Access – be anonymous and secure online.
