Restart Your Computer: Restart to apply the changes, and Windows Defender will be disabled permanently.

Option B: Using Registry Editor

Open Registry Editor: Press Win + R, type “regedit,” and press Enter.
Navigate to Defender’s Registry Key: Go to HKEY_LOCAL_MACHINE > SOFTWARE > Policies > Microsoft > Windows Defender.
Create a New DWORD: Right-click in the right panel, select New > DWORD (32-bit) Value, and name it DisableAntiSpyware.
Set Value to 1: Double-click DisableAntiSpyware and set its value to 1. Click OK.
Restart Your Computer: Once restarted, Windows Defender will be disabled.

Note: Modifying the registry can have significant impacts on your system. Proceed with caution and ensure you back up your registry before making changes.
