One of the issues is Windows Security failing to start. Fortunately, we have some quick fixes for you.
1. Reset or Repair Windows Security
Windows 11 comes with a native repair tool that can identify minor issues in apps and resolve them automatically. Windows Security is no exception. Here’s how to go about it:
2. Use SFC and DISM
Some Windows 11 apps (like Windows Security) can stop working due to corrupted or modified files. Fortunately, you can use SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools to detect and restore these files with the correct version. Here’s how to do so: Note: DISM might need to download some Windows files from Microsoft’s servers, so you should keep your PC connected to the internet.
3. Disable Background Apps
Unnecessary processes running in the background can interfere with Windows Security. If you suspect this might be the issue, use Task Manager to force these processes to stop. Also, you can perform a clean boot to make sure there’s no interference with Windows Security. Here’s how to go about it: Remember to enable the apps and processes you disabled after the issue is resolved.
4. Disable and Uninstall Third-Party Security Tools
If you have installed an additional antivirus on your PC, you probably should uninstall it. You see, Microsoft doesn’t allow you to run two or more security tools concurrently. Here’s how to uninstall third-party security tools:
5. Install the Latest Windows Updates
Updating your system brings new features, security patches, and bug fixes. If Windows Security is malfunctioning due to a bug in Windows, then updating your OS might help resolve the issue. Here’s how to download and install Windows 11 updates:
6. Restart Windows Security Center Service
“Windows Security Center Service” is an app that runs every time you boot up your computer. If the app fails to start due to a malfunction, you might not be able to access Windows Security.
