If Zoom has been installed on a centrally managed computer by the IT Service Center (ITSC) via "Software Kiosk" (i.e. "Portal Manager" [PC] or "Guided Software Installation" [Mac]), the updates are automated.
Zoom clients on self-managed computers must be updated by you within the Zoom application using the "Check for Updates" function under the personal profile (initials and online status, top right in the Zoom client).
