Microsoft launched a new security feature called Tamper Protection for the company's Windows Defender Antivirus solution in December 2018.
Tamper Protection, as the name suggests, protects certain security features from tampering. One of the barriers that Tamper Protection puts in place around security features blocks manipulations of setting changes that are made outside of the official Settings application.
Microsoft did not reveal much about the feature when it launched it in December 2018, but a new blog post on the official Tech Community website provides additional insight and the news that the security feature is being rolled out to all Home installations of Windows 10 that run the current feature update version Windows 10 version 1903.

Users must modify security settings directly through the Windows 10 user interface or via Microsoft enterprise management software such as Intune.
With Tamper Protection enabled, though, these attempts to change Windows Defender or Windows Security settings will be ignored or simply reset.
As Windows Defender automatically turns on when a third-party antivirus software is removed, it is even more important to enable Tamper Protection so that Windows Defender can adequately protect you.
Tamper Protection helps against manipulation of the operating system's real-time protection, cloud-delivered protection, the detection of suspicious Internet files, behavior monitoring, and security intelligence updates among other things, according to Microsoft.
