Windows Defender Remover is a batch script tool that disables and removes Windows Defender and related security components from Windows 8.x, Windows 10, and Windows 11.
The tool addresses the need to completely strip Windows Defender and its associated security infrastructure from Windows systems. It works by executing batch scripts that forcibly remove antivirus components including the Defender engine, definition updates, scanning tasks, and shell integrations. It also disables security features such as Virtualization-Based Security, SmartScreen, User Account Control file virtualization, Exploit Guard, Tamper Protection, and system mitigations. The project includes three main modules: an ISO Maker for creating custom Windows installations with Defender pre-disabled, a Remove Defender Engine script targeting the antivirus core, and a Remove Security App script targeting the Windows Security UI.
This tool is intended for users who want complete removal of Windows security features, typically those running custom or minimal Windows installations where antivirus protection is handled elsewhere or deemed unnecessary. It suits scenarios where system performance is prioritized over built-in security, such as on older hardware where mitigations like Spectre and Meltdown protections impact performance. Users should understand that removing these components significantly reduces the system's built-in security posture and should create a system restore point before proceeding. The README recommends this approach only for users who know what they are doing.
The project shows active maintenance with regular updates to support new Windows versions and security features. Development includes iterative refinement of removal procedures as Windows introduces new security components and mitigations. The tool receives ongoing adjustments to handle changes in how security features are integrated across different Windows releases.
