Tamper Protection is a security feature in Microsoft Defender that blocks unauthorized changes to important security settings, such as real-time protection, cloud-delivered protection, and other antivirus options. While this feature is useful for keeping a PC protected, there are times when users may want to turn it off temporarily, especially when troubleshooting Defender-related issues, installing certain system tools, or making advanced security changes that would otherwise be blocked.

 

Turning off Tamper Protection in Windows 11 is simple and only takes a few clicks.

Summary:

Disabling Tamper Protection in Windows 11 or Windows 10 is a straightforward process through the Windows Security app. It can be helpful when troubleshooting, testing, or making advanced Defender-related changes that are otherwise restricted.

After completing the task, turning Tamper Protection back on is strongly recommended to keep the system safer.
