Hello

The error code 0x80240034 you’re encountering is a common issue with Windows Update, and it can occur due to various reasons such as corrupted system files, issues with the Windows Update services, or network-related issues.

Here are some steps you can take to troubleshoot and potentially resolve this issue:

Run Windows Update Troubleshooter: This tool can automatically diagnose and fix common problems with Windows Update.

Check Windows Update Services: Ensure that the Windows Update services are running properly. You can check this by opening the Run dialog (Windows key + R), typing services.msc, and pressing Enter. In the Services list, look for Windows Update, Background Intelligent Transfer Service (BITS), and Cryptographic Services. Make sure these are running and their startup type is set to Automatic.

Run System File Checker (SFC) and DISM: These tools can fix potential errors or corruptions in your system files. Open Command Prompt as an administrator and type sfc /scannow to run SFC. After that, run DISM by typing DISM.exe /Online /Cleanup-image /Restorehealth.

Reset Windows Update Components Manually: This involves stopping the services mentioned in step 2, renaming the SoftwareDistribution and catroot2 folders, and then starting the services again.

Check Network Connection: If you’re using a Wi-Fi connection, try switching to a wired connection if possible.

Disable Third-Party Antivirus Temporarily: Sometimes, third-party antivirus software can interfere with Windows Update. Try disabling your antivirus software temporarily and check if the update succeeds.

Regarding your question about registry AU options, while certain Windows Update settings can be configured via the registry, it’s generally not recommended to modify the registry unless you’re confident in what you’re doing, as incorrect changes can cause serious issues. It’s unlikely that this issue is related to registry AU options.
