Common reasons for Windows Defender not working include third-party antivirus software conflicts, related services not enabled, system files corruption, or Group Policy restrictions. 1. Check whether there is third-party security software and uninstall it; 2. Make sure that the core service of Windows Defender is running and the startup type is automatic; 3. Use sfc and DISM commands to repair system files; 4. Advanced users can check whether Defender is disabled, and if controlled, administrator rights adjustment is required.

Windows Defender not working.

Windows Defender does not work, which may be caused by several common reasons. The most direct manifestations are that real-time protection is not enabled, virus scanning fails or error prompts are displayed on the interface. First confirm whether third-party antivirus software is installed. This type of software usually disables Windows Defender; if not, the problem may lie in the system settings, service running status, or permission configuration.

1. Check for third-party security software conflicts

After installing security software such as Kaspersky, Turfur, 360, many users found that Windows Defender was automatically shut down. This is the normal mechanism: Windows allows only one major security guard to run.

  • Solution :
    • Open Settings > Apps > Apps and Features
    • Find and uninstall installed third-party antivirus software
    • After uninstalling, restart the computer and check whether Defender returns to normal

If you don't want to uninstall third-party software, you can only continue to use the protection functions it provides, and don't expect to use two software to kill.

Sometimes, system update exceptions or manual service settings may cause the core service of Defender to be deactivated.

  • Operation steps :
    • Press Win R and enter services.msc to enter
    • Find the following services (probably more than one) in the list:
      • Windows Defender Antivirus Service
      • Windows Defender Security Center Service
    • If the status is "Stopped", right-click to select "Start"
    • If the startup type is not "auto", please change it to "auto"

If the service fails to start, it may be due to permission issues or system files are corrupted, you can try the next step.

3. Use the system file check tool to fix system problems

Windows Defender relies on system components and can cause it to fail to function properly if the system files are corrupted.

  • Execute the command :
    • Open Command Prompt as Administrator (CMD)
    • Enter the following two commands to execute:
       sfc /scannow
      DISM /Online /Cleanup-Image /RestoreHealth
    • After completion, restart the computer and check whether Defender is restored

This process may take a little time and do not interrupt during this period, especially when the network is slow.


4. Check Group Policy or Registry Settings (Applicable to Advanced Users)

If you are on a company computer or have your system policy modified by others, it is possible that Windows Defender is disabled through Group Policy.

  • View method :
    • Press Win R and enter gpedit.msc to enter
    • Navigate to:計(jì)算機(jī)管理>管理模板> Windows 組件> Microsoft Defender 防病毒
    • Check if "Close Microsoft Defender Antivirus" is enabled

If it is controlled by policy, it is difficult for ordinary users to change it by themselves unless you have local administrator permissions.


Basically, these common investigation directions. In most cases, it is a problem caused by third-party software conflicts or service abnormalities. The order of hands-on can be: uninstall other software → start the service → repair the system files. If you encounter special circumstances, consider group policy or registry settings.
