The Windows Update workflow has four core areas of functionality:
  • Scan
    • Orchestrator schedules the scan.
    • Orchestrator verifies admin approvals and policies for download.
  • Download
    • Orchestrator starts downloads.
    • Windows Update downloads manifest files and provides them to the arbiter.
    • The arbiter evaluates the manifest and tells the Windows Update client to download files.
    • Windows Update client downloads files in a temporary folder.
    • The arbiter stages the downloaded files.
  • Install
    • Orchestrator starts the installation.
    • The arbiter calls the installer to install the package.
  • Commit
    • Orchestrator starts a restart.
    • The arbiter finalizes before the restart.
