How do I fix the Windows Defender error code 0x80004004?
Got it. What else can I do if the previous steps don't work?
If those steps don't work, it's possible that there is a problem with your Windows operating system. You can try running the built-in troubleshooter. Go to "Settings", then "Update & Security", select "Troubleshoot", and choose "Windows Security". Follow the prompts to complete the troubleshooting process.
