Description of the Office Feature Updates task


Starting in Microsoft Office ProPlus build 16.0.11220.* or a later build, there are two new tasks:

  • Office Feature Updates
  • Office Feature Updates Logon

The Office Feature Updates task calls the "SDXHelper.exe" process in the background. You can view this process in Task Manager during the execution. This task runs in user context and polls Office services in the background. It doesn't cause any Office performance issues during startup.


If the "SDXHelper.exe" process is causing high CPU usage, try to repair your Office installation.

  • This task runs for every user for all Microsoft 365 Apps Channels. However, it downloads feature updates based on your defined policies.

    For example, Semi Annual Enterprise Channel (SAEC) 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.
