Thanks for joining the Intel communities.
I understand you have some questions about Intel(R) Management Engine Interface.
This is an interface that uses the Intel ME hardware features to enable an interaction between high- and low-level hardware systems in a system. This is one of the main components of the VPRO Remote Access technology by Intel.
Administrators can now handle the tasks without intervention of the human beings. Some applications like remote access require connection between low and high levels of hardware in the board. This is why Management Engine Interface drivers are needed.
It is well known that the Intel Management Engine Interface enables effectual communication between the Intel Management Engine firmware and the host operating system. The Driver installs the hardware required for proper functioning of interface.
