How do I permanently disable Windows Defender on Win11/Win10?
With YY-Toolkit: Antivirus tab → follow the guide to turn off Tamper Protection → press Disable antivirus (stays off until you restore). Without this app, follow these manual steps:
- Open Windows Security → Virus & threat protection → Manage settings.
- Turn off Tamper Protection first (confirm when prompted; other toggles may stay locked until you do).
- On the same page, turn off every protection toggle: Real-time protection, Cloud-delivered protection, Automatic sample submission, and similar items (names vary by Windows version).
- Those toggles alone may not stop background scans. For a full shutdown like this app: run services.msc as admin, stop and set to Disabled: Microsoft Defender Antivirus Service (WinDefend), Microsoft Defender Antivirus Network Inspection Service (WdNisSvc), and on Windows 11 Microsoft Defender Core Service.
- On Pro/Enterprise, you can also use Group Policy: Computer Configuration → Administrative Templates → Windows Components → Microsoft Defender Antivirus → Turn off Microsoft Defender Antivirus → Enabled (Home editions usually skip this).
- After installing your software, restore in reverse: set services back to Automatic and start them, then re-enable all toggles and Tamper Protection in Windows Security.
