  • This task runs for every user for all Office ProPlus Channels. However, it downloads feature updates based on your defined policies.

    For example, Semi Annual Channel (SAC) users are expected to receive updates on a six-month cadence. Therefore, this task doesn't schedule downloads of feature updates to run every few hours .
  • This task makes sure that Office installations can check for feature updates.
