Fix Windows Security Closes Immediately After Opening in Windows 11/10
If you find that Windows Security or Defender crashes immediately upon opening in Windows 11 or 10, you’re not alone. This guide will walk you through various troubleshooting steps to resolve this issue effectively, enabling you to use Windows Security seamlessly once again. By following these steps, you’ll learn how to perform scans, repairs, and adjustments to rectify the problem.
Step 1: Run Antivirus Scan at Boot Time
To address issues with Windows Security, initiating a boot-time antivirus scan can be essential. This method scans for malware that may be affecting system performance before the operating system fully loads.
- Access the antivirus software on your computer.
- Look for the option to perform a boot-time or offline scan.
- Follow the prompts to schedule and run the scan upon next boot.
Step 2: Use System File Checker (SFC)
The System File Checker is a built-in tool that repairs corrupted system files that may cause Windows Security to crash.
- Open Command Prompt as an administrator by searching for “cmd” in the Start menu, right-clicking, and selecting “Run as Administrator.”
- Type the following command and press Enter:
sfc /scannow - Wait for the process to complete and follow on-screen instructions.
Step 3: Run Deployment Imaging Service and Management Tool (DISM)
Dism.exe is a command-line tool that can fix Windows corruption errors. Run it after the SFC tool for better results.
- Open Command Prompt as an administrator as mentioned in Step 2.
- Execute the following command:
DISM /Online /Cleanup-Image /RestoreHealth - Allow the process to finish and restart your computer afterward.
Step 4: Repair or Reset Windows Security
If Windows Security continues to malfunction, consider repairing or resetting the app.
- Go to Settings > Apps.
- Locate Windows Security in the apps list.
- Select it and click on Advanced options, then choose Repair. If the issue persists, use the Reset option.
Step 5: Disable or Uninstall Third-Party Antivirus
Sometimes, conflicts with third-party antivirus solutions can hinder Windows Security. To resolve this:
- Open the Control Panel and select Programs.
- Find and uninstall any third-party antivirus programs, or temporarily disable them from their settings.
Step 6: Troubleshoot in Clean Boot State
A Clean Boot starts Windows with a minimal set of drivers and startup programs. This can help you determine if background programs are causing issues.
- Open the Run dialog (Windows + R), type
msconfig, and press Enter. - In the System Configuration window, select Selective startup and uncheck Load startup items.
- Go to the Services tab, check Hide all Microsoft services, and click Disable all.
- Restart your computer.
Step 7: Cloud Reset or Reset This PC
If none of the previous methods work, consider performing a cloud reset or a full reset of your PC. This reinstalls Windows, possibly resolving underlying issues that affect Windows Security.
- Navigate to Settings > System > Recovery.
- Under the Reset this PC section, click Get Started and select either Cloud Reset or Local Reset.
Extra Tips & Common Issues
To enhance your troubleshooting process:
- Always back up your important data before performing a reset.
- Check for Windows updates regularly to ensure you have the latest fixes and patches.
- If issues persist, review system logs via the Event Viewer for specific error messages that may guide further troubleshooting.
Common mistakes include skipping the SFC scan or not performing a thorough uninstall of third-party antivirus software, so take your time to ensure everything is done correctly.
Following these steps can help you restore full functionality to Windows Security, ensuring that your system remains protected. If you continue to face issues, exploring further support resources may be necessary.
