When The Tamper Protection feature is enabled, the Microsoft Defender antivirus program is blocked from disabling its components, such as Real-Time Protection, Cloud Protection, and more.

Tamper Protection blocks changes to the default security settings. Specifically, changes to individual settings in Registry Editor, command line, PowerShell, and Group Policy Editor are blocked.

Part 1: Turn off Tamper Protection
