Microsoft Office 2010, 2013, and 2016 downloaded from http://software.oit.gatech.edu require activation against the campus KMS servers.  If this was installed by the TSO Help Desk, the initial activation should have already been done; as long as the computer is connected to the campus network (via non-LAWN wired connection or via the VPN) at least every 180 days, Office should remain active.  However, if the end user performed the installation or the grace period lapsed, it must be manually activated.  Here is how to do that.
