One of the primary causes of Windows Update Error 0x80070643 is often attributed to conflicts with security software.

Windows Defender, being the built-in antivirus solution, plays a crucial role in system protection. However, an outdated version might inadvertently clash with the latest Windows updates. To address this, it's imperative to ensure that Windows Defender is not only enabled but also up to date.

Start by navigating to the Windows Security app. Check for updates and make certain that your antivirus definitions are current. If an update is available, initiate the process and allow Windows Defender to bolster its defenses.

Following this, run a comprehensive system scan to detect and eliminate any potential threats that might be causing interference with the update process. By maintaining an updated and secure antivirus environment, you create a robust foundation for successful Windows updates.

2. Clear Update Cache:

The SoftwareDistribution folder serves as a temporary repository for Windows Update files. However, over time, this cache can become cluttered with outdated or corrupted files, leading to issues with the update process.

To address this, manually clearing the contents of the SoftwareDistribution folder can prove to be an effective solution.

Begin by stopping the Windows Update Service. Once halted, navigate to the C:\Windows\SoftwareDistribution directory and delete all its contents. This action essentially clears the cache, allowing Windows Update to start anew with fresh files.

After completing this step, restart the Windows Update Service and attempt to install the pending updates. This simple yet powerful approach often resolves issues related to corrupted update files, paving the way for a seamless update experience.

3. Use Windows Update Troubleshooter:
