Winbox is a small utility that allows administration of MikroTik RouterOS. While newer versions exist, Winbox v3.11 remains a popular and stable release used by network administrators worldwide. It is widely regarded for its reliability on older hardware and specific legacy configurations.
One hidden gem of version 3.11 is that its scripting interface is incredibly stable. You can launch it via command line for automation:
winbox64.exe -m router1.mikrotik.com admin password123 !/system script run backup
