Open the folders inside Registry Editor by using the arrows next to the folder icon. You will want to navigate to:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Add New Registry Value

Once you select the Windows Defender folder, you will right click inside the blank space inside the right panel of the window and hover over New, then click the option that says ‘DWORD (32-bit Value)’.
