Menu path: Setup > System > Update > Partial Update

The IGEL mechanism for partial updates allows you to make changes to IGEL thin clients with Windows Embedded Standard without transferring the complete system via snapshot. The changes are made with the help of scripts which are downloaded to the clients and the executed through a scripting engine on the basis of the script language Lua.

  • Enable partial update

    The service upd-service is launched. Partial updates can be carried out.

    The service upd-service is stopped. Partial updates cannot be carried out.

  • Enable auto-update on boot

    The partial update will be installed automatically the next time that the thin client reboots.

    The automatic update when booting function should only be enabled if it is needed.
  • Protocol: Protocol with which the partial update is downloaded from a server or obtained from a local directory
    Possible values:
    • HTTP
    In order to provide the partial update, the server must be configured so that it accepts requests regardless of the MIME type.
    • HTTPS
    In order to provide the partial update, the server must be configured so that it accepts requests regardless of the MIME type.

    • FILE: The partial update will be obtained from a local storage device, e.g. from a USB storage device.
  • Host: Host name or IP address of the server from which the partial update will be downloaded
  • Port: Port of the server from which the partial update will be downloaded
  • Path: Directory path on the server from which the partial update will be downloaded
  • Username: User name for the server from which the partial update will be downloaded
  • Password: Password for the server from which the partial update will be downloaded
  • Check for updates: The thin client searches in the selected source for available updates.
  • Show installed packages: The partial updates already installed are shown.

To install a partial update, proceed as follows:
  1. Enable the option Enable partial update.
  2. Select the protocol.
  3. Under Host and Path, specify the source for the partial update.
  4. Click on Apply to save the settings.
  5. Click on Check for updates to search the source for updates.
    When the download is complete, the system will reboot. The partial update will be available after the reboot.
    From Version 3.12.100, the thin client notifies the UMS about installed partial updates; this information is supported from UMS Version 5.3.100.
