WinDivert is a software package that provides user-mode packet capture, redirection, modification, and re-injection for Windows Vista/Windows 7. It provides similar functionality to divert sockets for FreeBSD/MacOS, and NETLINK sockets (with netfilter-queue) for Linux. It is also similar to some commercial packages, such as WinPkFilter, for Windows.
