What Is Tamper Protection on Windows 11?
The Windows Security app on Windows 11 has a Tamper Protection feature that can prevent unauthorized changes to Windows Security that are not modified directly through the application. It offers an additional layer of protection during hacker attacks and malicious apps trying to disable the security features. But it can also block you from making changes outside the Windows Security app. For instance, when Tamper Protection is turned on, you may be unable to use commands in Command Prompt or Windows PowerShell to change the configuration of Microsoft Defender Antivirus, Firewall, etc. You can’t even disable Microsoft Defender Antivirus using the Group Policy Editor.
