Hello Carlos,
Thanks for reaching out to Microsoft Q&A forum Support.
If I understand you correctly, you're encountering Windows Update error 80072EFE, which typically signals a connection issue between your device and the Windows Update servers.
Apply these diagnostic steps to address the error,
- Checking your internet connection helps to ensure your device is connected to a stable network, you can restart the router or switch to a different network if possible.
- To run the Windows Update Troubleshooter, go to Settings > Update & Security > Troubleshoot > Additional troubleshooters then select Windows Update and run the troubleshooter.
- Sometimes security software blocks update connections temporarily try to disable firewall/Antivirus and try updating again.
- Also, check proxy settings by going to the Internet options > connections > LAN Settings and uncheck “Use a proxy server” if enabled.
Best wishes,
