How to fix Windows Defender will not update
1: Initial correction
Before moving on to a more detailed explanation, let's follow some basic tests and procedures:
Check to see if you have any other security software installed, as this will stop Windows Defender and prevent you from getting updates. Remove any anti-malware software currently installed on your computer.
Check for updates through the Windows Defender Update interface, and if that doesn't work, try Windows Update; To do this, click the shield icon in the notification area, select Virus and Threat Protection, and then check for updates.
Install all pending updates and restart your computer before retrying the Windows Defender update; Set up Windows Defender to automatically check for updates.
Run Troubleshooter for Windows Update.
2: Install Manually Update Definition
Updates are often delivered by Microsoft via Windows Update, Automatic Updates, or Windows Server Update Services (WSUS). Due to issues with these services, Windows Defender will not update in some cases.
Manually update the definition in this situation as mentioned above. If you are able to install updates manually, the problem is due to a Windows Update issue. You can visit the Windows Security Portal for more updates.
