What WindowsSpyBlocker is

WindowsSpyBlocker is a free, open-source Windows application for blocking telemetry and tracking activity. It captures and interprets network traffic, then forms rules from interactions among services and traffic destinations. Its components include rules for Windows telemetry and data collection, plus an app that can apply, show, or remove its network rules in the Windows firewall. Separate hosts lists cover spy, update, and extra entries, including IPv6 files. Downloads are available through GitHub releases, Chocolatey, and Scoop, with automatic updates supported by the package managers. The project documents formats for the Windows firewall, hosts, DNSCrypt, several other firewalls, OpenWrt, Proxifier, and simplewall. Its FAQ says releases are scanned by VirusTotal. The project is licensed under MIT. The newest release listed in its changelog is version 4.39.0, dated May 16, 2022. The FAQ warns that firewall or hosts rules may need removal if Windows Update cannot connect.
