Fix Windows Security Issues in Windows 11 with a Reset

You can fix Windows Security issues in Windows 11 by resetting the app.

Windows Security is the built-in tool that monitors your PC’s security and health. When it acts up, like closing unexpectedly or refusing to open, a reset often solves the problem.

Resetting this app clears out any corrupted temporary files or data, bringing it back to its original settings. This won’t touch your personal files or any antivirus programs you’ve installed.

This troubleshooting step is particularly useful if you’re seeing errors after a recent Windows 11 update, such as one for build 22621.
