To use the ARP command in Windows, open the Command Prompt and type `arp -a` to display the current ARP table, which associates IP addresses with their resolved physical MAC addresses on your network. If you want to add a static ARP entry, use `arp -s <IP address> <MAC address>`, replacing `<IP address>` and `<MAC address>` with the actual values. To remove an entry, type `arp -d <IP address>`. Remember, managing ARP entries is mostly needed for network diagnostics or when configuring static mappings for devices.
