That update comes in the form of "Tamper Protection" that will lock down malicious and unauthorized changes to the security settings of Windows Defender. Changes of the type that the recent Nodersok Windows "Zombie Attack" attempts to make; the disabling of Windows Defender itself. First introduced with the May 2019 Windows 1903 update, Microsoft is to now enable the feature on all devices by default. "We’re currently turning on the feature gradually," Jha said, but you can check from the Windows Security app (search Windows for "Windows Security") in the Virus & Threat Protection options for Windows Defender users and enable it if available anyway. This is an important feature update even if you don't use Windows Defender for your antivirus protection as Windows 10 will default back to its security tool if your third-party one is removed.
