Overview​

This script removes the "Windows Security" app 1, known as SecHealthUI 2 3. This app serves as the interface for Windows Security 2, helping users monitor and manage their computer's security 4. It provides alerts and guidance on vulnerabilities through the Action Center 4.

However, uninstalling the "Windows Security" app has significant implications:

  • It may increase vulnerability to threats by no longer alerting users about security issues or communicating updates through the Action Center 4.
  • Disabling its interface can hinder the effective management of security settings, including tamper protection 5.

Despite these risks, removing the app can enhance privacy in several ways:

  • Less personal data collection: Reduces the collection and display of personal and system data such as threats 6, limiting information used to analyze user behavior.
  • More control over security settings: Encourages managing security settings programmatically, reducing accidental misconfigurations and unauthorized access.
  • Decreased notifications and alerts: Reduces the number of notifications that may expose sensitive information.
  • User choice in security tools: Offers freedom to choose alternative privacy-focused security measures.
  • Increased anonymity: By uninstalling the app, users reduce the amount of data shared under the terms of Microsoft's privacy policy, which allows Microsoft to collect and share data with external entities when the app is in use.

The package is named Microsoft.Windows.SecHealthUI on Windows 10 and Microsoft.SecHealthUI on Windows 11 1 2.

It operates independently from individual Defender features 7 and is updated separately from the operating system 8. Uninstalling it does not disable Microsoft Defender Antivirus or Firewall 9, and Windows will continue sending security notifications unless disabled separately 10.

Caution

Uninstalling "Windows Security" app can expose your system to threats and limit your ability to configure security settings. It should only be done with a full understanding of the consequences.

  1. Not Advised

    This script should only be used by advanced users.

    This script is not recommended for daily use as it breaks important functionality.

    Consider creating a system restore point before doing any changes.

  2. Security Trade-off

    This action prioritizes privacy over certain security features. It's not recommended and should only be used by advanced users after understanding its implications.

    Increased Privacy

    Enhanced privacy through reduced data collection and tracking

    Decreased Security

    Some security features will be disabled or limited

    This script can be reversed, this allows you to restore the default system security.
