Windows Security Not Opening

Hi rncn183,

Sorry to hear you're experiencing this issue!

Step-by-Step Troubleshooting

Step 1: Restart Your PC

Restart Your PC:

Sometimes, a simple restart can resolve issues with applications not opening properly. Restart your PC and try opening Windows Security again.

Step 2: Check for Windows Updates

Ensure Windows is Up to Date:

Go to Settings > Update & Security > Windows Update.

Click on Check for updates and install any available updates.

Restart your PC if any updates were installed.

Step 3: Run System File Checker (SFC) and DISM

Run System File Checker (SFC):

Press Win + X and select Windows Terminal (Admin).

Type the following command and press Enter:

shell

Copy code

sfc /scannow

Wait for the scan to complete and follow any on-screen instructions.

Restart your PC.

Run Deployment Imaging Service and Management Tool (DISM):

Open Windows Terminal (Admin) again.

Type the following commands one at a time and press Enter after each:

shell

Copy code

DISM /Online /Cleanup-Image /CheckHealth

DISM /Online /Cleanup-Image /ScanHealth

DISM /Online /Cleanup-Image /RestoreHealth

Wait for each process to complete.

Restart your PC.

Step 4: Reset Windows Security App

Reset the Windows Security App:

Go to Settings > Apps > Apps & features.

Scroll down and find Windows Security in the list.

Click on it and select Advanced options.

Scroll down and click Reset.

Step 5: Re-register Windows Security App

Re-register the Windows Security App:

Open Windows Terminal (Admin).

Type the following command and press Enter:

Get-AppxPackage Microsoft.SecHealthUI -AllUsers | Reset-AppxPackage

Restart your PC.

Step 6: Check for Conflicting Software

Check for Conflicting Software:

Sometimes third-party antivirus or security software can conflict with Windows Security.

Temporarily disable or uninstall any third-party antivirus software and try opening Windows Security again.

Please try these steps one at a time and let me know if any of them resolve the issue. If the problem persists, I have more solutions we can try.

Best regards,
