While Windows Security is an excellent security application, it can sometimes encounter bugs that prevent users from running scans. Many users have recently reported issues with Windows Defender not opening after upgrading to Windows 11. If you’re facing problems with the security app, it’s important to address them promptly. Here are some effective solutions to resolve the issue.
1. Restart Your Windows 11 PC
If you’re having trouble with Windows Security not opening or running scans, the first step is to restart your computer. A simple reboot can often resolve many issues, so make sure to try this before moving on to other solutions. Click the Power button and select “Restart.”
2. Disable Other Security Programs
Windows 11 automatically disables Windows Security when it detects a third-party security application. If you’ve recently installed another security program, it may prevent Windows Security from functioning properly. To enable full scans and real-time protection, you’ll need to disable any other security software you have installed.
3. Restart the Security Center Service
The Security Center service is crucial for the real-time protection provided by Windows Security. If this service is disabled, the app won’t function correctly. To restart the Security Center service, follow these steps:
1. Press the Windows Key + R to open the RUN dialog box.
2. Type `services.msc` and hit Enter.
3. In the Services window, locate “Security Center.”
4. Right-click on “Security Center” and select “Restart.”

4. Run SFC and DISM Scans
The SFC (System File Checker) and DISM (Deployment Image Service and Management) tools can help identify and repair corrupted system files that may be affecting Windows Security. Here’s how to run both commands:
1. Search for “Command Prompt” in Windows 11, right-click it, and select “Run as administrator.”
2. In the Command Prompt, type the following command and press Enter:
“`
sfc /scannow
“`
3. If the SFC scan finds errors, run the following command to repair the system image:
“`
DISM /Online /Cleanup-Image /ScanHealth
“`
These commands should help resolve issues with the Windows Security app.
5. Reset the Windows Security App
If Windows Security is still not functioning properly, you can reset the app. Here’s how:
1. Open the Settings app and click on “Apps.”
2. On the right side, select “Installed Apps.”
3. Locate the Windows Security app and click the three dots next to it.
4. Choose “Advanced options” from the menu.
5. Click on the “Reset” button on the next screen.
6. Reset Your Windows 11 PC
If none of the previous methods work, you may need to reset your Windows 11 PC. This will restore your system to its factory default state, removing all installed applications. Be sure to back up your important files before proceeding to avoid data loss.
1. Click on the Start menu and select “Settings.”
2. Navigate to “System” > “Recovery.”
3. Click on the “Reset PC” option.
4. Choose whether to keep your files or remove everything. It’s recommended to select “Keep my files.”
After the reset, try running the Windows Security app again. It should function correctly this time. Follow the on-screen instructions to complete the reset process.
