BT Updater 3.5 release notes

When installing a product for a subscription that runs an installer, and the installer requires a pending reboot:

• Case 1: Auto Reboot is OFF
  • The subscription is not marked as published.
  • The machine does not reboot automatically.
  • The activity log shows: "update deferred (reboot needed)".
  • Once the user manually reboots the machine and it starts back up, it automatically tries to publish the subscription again.
• Case 2: Auto Reboot is ON
  • The subscription is not marked as published.
  • The machine automatically reboots.
  • The activity log shows: "update deferred (reboot needed)"
  • After the reboot, it automatically tries to publish the subscription again.

Improve user feedback when a reboot is recommended:

• Added notifications to inform user that reboot is recommended.
• Added a banner to inform user that reboot is recommended.

When installing a product for a subscription that runs an installer, and any of the following system settings indicate a reboot is pending:

• A reboot is required by Windows Update.
• A reboot is pending from Component-Based Servicing.
• A system update is scheduled on boot.
• There are pending file rename operations.

Then:

• The updater sets a global reboot flag.
• The Updater UI displays a banner message saying "Reboot recommended".
• After the machine is rebooted, the global reboot flag is resets the banner disappears.

The system uses the installer’s recommended reboot exit code as a natural signal to pause.

When the installer returns this code:

• The updater knows a reboot is required and does not mark the install as complete.
• The installation automatically retries after the machine is rebooted.
• If the user clicks "Update Now" before rebooting, the installer may return the same reboot recommended code again, since the reboot still hasn’t occurred.
