To assist all Windows customers, including those who are not running Windows Security, Microsoft provides Microsoft Defender Offline.
Microsoft Defender Offline
Microsoft Defender Offline runs outside of Windows to remove rootkits and other threats that hide from the Windows operating system. This tool uses a small, separate operating environment, where evasive threats are unable to hide from antimalware scanners.
With Windows 10 and 11, Microsoft Defender Offline is built in to the operating system and can run from Windows Security. It is provided as a separate download for previous versions of Windows.
