On my reading list, because I saw it suddenly enabled on a domain based Windows network:
[WayBack] Enable Block at First Sight to detect malware in seconds | Microsoft Docs
Enable the Block at First sight feature to detect and block malware within seconds, and validate that it is configured correctly.
It seems to have been introduced early 2018: Windows Defender – Wikipedia: Advanced Features
Windows 10’s Anniversary Update introduced Limited Periodic Scanning, which optionally allows Windows Defender to scan a system periodically if another antivirus app is installed.[5] It also introduced Block at First Sight, which uses machine learning to predict whether a file is malicious.[21]
There is a BAFS – Windows Defender Testground for which you need a Microsoft account.
