How to fix KB5019959 fails to install in Windows 10?

Issue: Hi, I have launched a Windows update KB5019959, and it didn't get through. Instead, I received an error that said that the update process failed. Is there anything that can be done to fix it? The answer is much appreciated.

Solved Answer

When Windows 10 was introduced back in 2015, it was upgraded to a service level, entailing Microsoft to deliver updates at a predetermined frequency. Users should routinely look forward to new features, security vulnerability[1] patches, improvements to existing features, and bug fixes.

KB5019959 (along with KB5019966) was released on November 8, 2022, as a part of its Patch Tuesday[2] routine. They consist of cumulative updates for OS build 19042.2251, 19043.2251, 19044.2251, and 19045.2251 and were designed for Windows 10 versions 22H2, 21H2, 21H1, and 20H2.[3]

KB5019959 is another important update from Microsoft that is meant to fix numerous security vulnerabilities, twenty bugs, and other performance issues. This is one of the main reasons why users are keen to install it, although this process is not always successful, as some reported the update failing.

Windows update errors and update installation failures are relatively frequent occurrences, which many are accustomed to. On the other hand, some users rarely encounter update issues. We have previously discussed installation failures of KB5018410, KB5018418, KB5018499, and many others. While the updates differ, the circumstances they fail at are similar, more or less, although sometimes they may be update-specific.

System file corruption is among the most common reasons for Windows update installation failures, so we recommend attempting to repair these issues first if they exist. In order to check the PC for system file integrity, you should run some commands via the elevated Command Prompt:

  • Type cmd in Windows search
  • Right-click on Command Prompt and pick Run as administrator
  • When User Account Control shows up, click Yes

Many users who encountered difficulties installing Windows updates concluded that the presence of third-party security software on the system interfered with the procedure's success. An overly aggressive anti-malware program may occasionally tamper with connections to Microsoft servers and stop the update from being applied.

Furthermore, anti-malware software makes a plethora of changes to your system that could potentially cause problems. Because of this, we recommend temporarily uninstalling or disabling your security software and then attempting to download the update again.

Solution 3. Troubleshoot

If you haven't yet run the built-in Windows Update troubleshooter, you should definitely do it as follows:

  • Type Troubleshoot in Windows search and press Enter
  • Choose Additional troubleshooters
  • Locate Windows Update in the list
  • Click it and select Run the troubleshooter
  • Once the troubleshooter finishes its scan, apply the fixes suggested and restart your device.

Don’t pay ransomware authors – use alternative data recovery options

Malware attacks, particularly ransomware, are by far the biggest danger to your pictures, videos, work, or school files. Since cybercriminals use a robust encryption algorithm to lock data, it can no longer be used until a ransom in bitcoin is paid. Instead of paying hackers, you should first try to use alternative recovery methods that could help you to retrieve at least some portion of the lost data. Otherwise, you could also lose your money, along with the files. One of the best tools that could restore at least some of the encrypted files –  Data Recovery Pro.
