WinDivert allows user-mode applications to capture/modify/drop network packets sent to/from the Windows network stack.
Riverbed Technology: "WinPcap Has Ceased Development. We recommend Npcap. The WinPcap project has ceased development and WinPcap and WinDump are no longer maintained. We recommend using Npcap instead".
