KB5022836 fails to install
on Windows

Hello, I have a problem with Windows update KB5022836, which fails to install. I have been trying for several days now but to no avail. Any ideas on what to do to resolve this?

Windows updates are a critical aspect of maintaining a healthy and secure operating system. Microsoft releases these updates regularly to address security vulnerabilities, improve performance, and introduce new features. Windows updates work by downloading the latest software patches, bug fixes, and updates from Microsoft servers and installing them on your computer.

Windows updates are needed because they address known security issues and vulnerabilities, which can potentially put your computer and data at risk. These updates provide protection against various threats, such as malware, viruses, and cyberattacks, by patching security holes and strengthening your system's defenses. Windows updates also help to optimize system performance and address software bugs, which can improve the stability and speed of your computer.

Unfortunately, Windows updates can sometimes fail to install, leading to frustration and potential security risks. On February 14, 2023, Microsoft released a critical update, KB5022836, to address multiple security issues, including vulnerabilities that could allow attackers to execute code remotely on your computer. However, many users have reported issues with installing this update.

Many people noticed that they are getting an installation error 0x80070103 (although this can vary), and it is related to Realtek Semiconductor and a few other extensions.

The failure to install KB5022836 may be caused by various issues, such as corrupted update files, system incompatibility, insufficient storage space, or conflicts with other software. To address this issue, users can try various troubleshooting steps, including running the Windows update troubleshooter, checking for system compatibility, freeing up storage space, and temporarily disabling security software.
