Introduction of new WinIoT 2.x Configuration

Wyse Management Suite 4.1 supports new WinIoT 2.x configurations through a new configuration user interface, which provides an enhanced user experience. The new interface includes a search function that enables you to locate configuration options easily, saving time and effort.

ConfigUISupport.exe is required to recognize any device as a WinIoT 2.x policy-enabled device. For the WinIoT devices to be managed with the WinIoT2.x policy, deploy the ConfigUI.exe package from WMS. This will require the installation of the Dell Application Store in the same policy.

For the public cloud environment, the new interface is applied automatically. On-Prem or local WMS, apply all ConfigUI updates to your WMS install. This functionality is supported when you upgrade Wyse Device Agent to version 14.6.9.x or later versions and Wyse Easy Setup to version or later.

NOTE: After transitioning from WinIoT (Legacy WES) to WinIoT 2.x, you must redo all configurations.

Benefits / Features

Enhanced user experience: The new policy provides a fresh and intuitive user interface, making it
easier for users to navigate and utilize the WMS effectively.

  • Search function: The new UI includes a search function that enables users to locate configuration options more easily, saving time and effort.
  • Autonomous feature updates: After the upgrade, IT administrators can upload the newer Config UI schema package to the WMS server and update the client agent by deploying the latest version of
    WDA. You do not need to upgrade the WMS server to support new features.
  • Reset Policy: The reset policy resets the entire page’s configuration and the entire policy, which will reset the configurations for all parameter groups. Both options are not part of the legacy policy.
    Only the configured parameters will be applied to the device. The parameters not configured from WMS, or the default values will not be applied on the device.
  • The new Windows IoT User Interface has a similar look and feel to ThinOS and DHC features. The features are grouped to help with easier navigation of configurations.

There is a key feature in WES 2.x that provides the ability to update Windows IoT Microsoft Updates using UWF Service Mode. This feature will reboot the device and apply relevant Windows IoT updates when applied or scheduled. Depending on how many updates are required, it may take 2 or more updates to patch Windows IoT fully.

“Transition from the WinIoT (WES) policy to WinIoT 2.x” discusses the transition of Windows IoT configuration policies in Dell Wyse Management Suite to the latest 2.x policies. Here’s a summary of the key points:

  1. Introduction: The document introduces the transition of Windows IoT configuration policies in Dell Wyse Management Suite to WinIoT 2.x policies. It outlines the renaming and benefits of these policies and provides step-by-step guidance on transitioning to the latest 2.x policies.
  2. Benefits to Customers: The new WinIoT 2.x policies offer an enhanced user experience and a more intuitive interface. They include a search function for easier configuration navigation. These policies also support autonomous feature updates and a reset policy feature.
  3. Supported Platforms: The document lists all supported platforms and binary requirements for the new WinIoT 2.x policy, including specific Windows versions and Dell hardware.
  4. Transition Process: It provides detailed steps for converting WinIoT (WES) devices to WinIoT 2.x devices, involving device registration, software deployment, and configuration.
  5. Customer Impact: The transition may require redoing all configurations. Only ConfigUI-enabled devices can be managed by the new WinIoT 2.x policy.
  6. Recommendation: Dell recommends transitioning to WinIoT 2.x policies, as new WinIoT-related features will only be available in these policies going forward. Legacy WinIoT (WES) policies will not receive new feature updates.
  7. FAQ: The FAQ section addresses common questions about policy conflicts, device compatibility, and how devices determine which configuration to use based on their software versions.

Reimaging Dell Thin Clients with New ISO formatted image

Dell recently moved to the ISO format of their ThinOS firmware; this format will not work with their Dell Wyse USB Imaging Tool. You can now reimage Dell OptiPlex and Latitude Thin Clients using Rufus or the Dell OS Recovery Tool. Steps using the Dell OS Recovery Tool are listed below.


  1. Download Dell OS Recovery Tool at
  2. Run the .exe file on the system to create the USB drive. The Dell OS Recovery Tool Application installer opens. (DO NOT RUN ON THINCLIENT)
  3. Click INSTALL.
  4. After the installation is complete, open the Dell OS Recovery Tool.
  5. Locate and Select SWITCH TO ADVANCED RECOVERY displayed at the bottom of the tool.
  6. In Select an OS image, browse to the ISO file that you downloaded and extracted, and then click NEXT.
  7. Select the USB drive that you want to format from the USB drive dropdown.
  8. Check the “I understand that the selected drive will be reformatted and existing data will be deleted” box.
  9. Click BURN OS.
  10. Remove the USB drive and connect it to the OptiPlex or Latitude system you want to reimage, make sure that it is powered off, on which you plan to install ThinOS. After connecting the USB drive, turn on the system.
    NOTE: After the USB drive is removed, the Dell OS Recovery Tool returns to the screen displayed in Step 5.
  11. Press F12 at boot up until you see the Dell logo and Preparing one-time boot menu… displayed at the top right corner. The boot menu opens.
  12. Select the USB drive from the UEFI Boot Devices list in the boot menu.
    NOTE: If you cannot select the USB drive, ensure that the Enable USB Boot Support option is enabled in BIOS.
  13. Enter the BIOS password if prompted. The default password for most Dell thin clients is Fireport.
  14. The thin client boots with a warning message and a 60-second countdown window is displayed.
    Wait 60 seconds or click OK to install the ThinOS image and application packages. The thin client reboots automatically. Click Manually to display the ThinOS image and application packages list. Select the ThinOS image and the application packages that you want to install and click OK to install these files. The thin client reboots automatically.
  15. The system continues imaging and reboots automatically once complete.
    NOTE: If you see the error “Fatal Error: Please make sure TPM or PTT is set to ON in BIOS.”, please turn TPM or PTT on in BIOS to continue installation.
