SimpleWall: A Lightweight Alternative to Windows Firewall

SimpleWall is a lightweight (<1MB) Windows firewall alternative compatible with Windows 7 SP1 and later. Based on the Windows Filtering Platform (WFP), it lets users create custom network rules, block Windows telemetry, and supports features like WSL. It boasts a simple interface, supports permanent and temporary rules, and requires manual filter disabling upon uninstallation. SimpleWall works independently of Windows Firewall and is free and open-source.
