Facing the Windows Update error 80004002 on Windows 10 can disrupt your system’s ability to download essential updates. However, this common issue can be resolved with the right troubleshooting steps. Our concise guide provides effective methods to fix this error, ensuring your Windows 10 system stays updated, secure, and performing at its best. Follow along to quickly get back on track.

How to Fix Windows Update Error 80004002

1. Check your system for software conflicts

To begin with, you should rule out software conflicts. The thing is, some of your apps might be on very bad terms with the Windows Update Agent.

So, does the code 80004002 appear only when a particular piece of software starts up on your computer? Are there any programs running in the background of your system while your Windows Update is having issues? 

These are the questions that may help you succeed in troubleshooting your problem.

Therefore, the first the thing you should do is visit your Task Manager:

  • Press the Ctrl + Alt + Delete shortcut -> The Windows Security screen will open.
  • Click on “Task Manager” -> Navigate to the Processes tab.
  • Carefully review the list of running processes and temporarily disable those that are non-essential for system operation to see if the update issue resolves. Remember to enable them again after testing.

Another manipulation that is worth trying involves disabling your non-Microsoft antivirus software, as it may be behind your update issues. If it turns out to be true, you may need to look for another antivirus that is fully compatible with all Windows processes, such as Auslogics Anti-Malware. Moreover, the software can run alongside your other anti-malware programs.

2. Scan your PC for malware

Evil never sleeps, you know. That means some stealthy piece of malware might have sneaked into your system and caused your Windows Update to malfunction. To eliminate this kind of issue, you should run a system scan:

  • Click on your Start button -> Move to the Settings gear.
  • Navigate to the Update & Security section -> Select “Windows Defender” -> Click Full scan.

Bear in mind that fighting against malware takes a lot of skill and effort, so you need a reliable tool to do away with such a powerful enemy. For instance, Auslogics Anti-Malware is designed for such challenges: it will hunt down and remove even the most cunning threats, and there won’t be any confrontation or tug of war with your main antivirus product.
