Methods On How to fix Windows Defender Won’t Update
Method 1: Preliminary Corrections
Before we get into the more extensive explanations, let’s go through some basic checks and procedures to follow:
Check to see whether you have any other security software installed, as this will stop Windows Defender and prevent it from receiving updates. Remove any anti-malware software that is 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 so, click the shield symbol in the notification area, select Virus & Threat Protection, and then Check for updates. Install all pending updates and restart your computer before trying the Windows Defender update again; Set Windows Defender to check for updates automatically. Run the troubleshooter for Windows Update.
Method 2: Install Update Definitions Manually
Updates are often delivered by Microsoft via Windows Update, Automatic Updates, or the Windows Server Update Service (WSUS). Because of issues with these services, Windows Defender won’t update in some circumstances. Manually update the definitions in this situation, as mentioned above. If you were able to manually install updates, the problem is due to a Windows Update issue. You can visit Windows Security Portal for more updates.
Method 3: Set the Windows Defender Service to Automatic Mode
Step 1: Open the Run box by pressing the Windows key + R keyboard shortcut.
Step 2: Type services.msc into the search box followed by Enter Key
Step 3: Right-click the Windows Defender antivirus service and select Properties.
Step 4: Make sure Service Status is up and functioning.

Step 1: Press the Start button.
Step 2: In the search box, type cmd.
