Release Notes - UIU Plug-ins 2.0 with MDT - Core Functionality Update Bookmark

November 11 2019 - RELEASE
Includes UIU plug-in for MDT version
Includes UIUPrep version

This is an update of the UIUPREP application ONLY.

New Feature: Continue on Error Control Compliance

In accordance with the SCCM(MDT) Task Sequence engine, the UIUPREP application will now return an error code (1) in the event that a condition required for the UIU to function efficiently or completely has not been satisfied. SCCM and MDT users should be able to control whether or not Task Sequences continue under the "Options" panel of their UIU Deployment Configuration step via the "Continue on error" control.

UIU Driver Database Review

Our Support team has completed a comprehensive review of the UIU Driver Database, particularly with respect to its inclusion of unsigned drivers. In previous versions, when the "Signed Drivers Only" option had been selected, unsigned drivers may have been delivered to target machines but not employed. As of UIUPREP version, handling of unsigned drivers has been optimized to ensure that they are not even delivered to target machines when the "Signed Drivers Only" option has been selected.

Due to security upgrades, UIU License Keys with expiration dates ≥ Jan 1, 2020 will only be valid with the following product versions of the UIU (or newer):

UIU 5:
UIU Plug-in for SCCM: (incl. UIUSMS.DLL v2.2.1.0)
UIU Plug-in for MDT: (incl. UIUSMS.DLL v2.2.1.0)
UIU Classic Mode:

Note: Each of these products employ the UIUPREP executable and as such the version of UIUPREP.EXE must be ≥

WARNING: The UIU Classic (4.x) Product will not function using UIU License Keys with expiration dates ≥ Jan 1, 2020

REMINDER: New Feature - Task Sequence UIU License Key Updating

The UIU plug-in updating feature has been upgraded to not only update the MDT plug-in within the framework of MDT (ts.xml), the service will also update the UIU license key within every MDT task sequence that contains the UIU Deployment Configuration element, requiring no Administrator interaction with MDT task sequences post-UIU updates.

Note: In previous versions of the UIU plug-in for MDT, after the plug-in had been updated using the UIU Plug-in Manager, each MDT task sequence that integrated the UIU Deployment Configuration element required an "Apply" event in order to use the UIUPM-updated UIU license key.

Supported MDT builds

  • Microsoft Deployment Toolkit (MDT), build 8450 - 6.3.8450.1000
  • Microsoft Deployment Toolkit (MDT), build 8456 - 6.3.8456.1000

REMINDER: Requirements Change - .Net Framework Version Upgrade

The UIU Plug-ins 2.0 with MDT (as of UIU 2.2.2.x) now requires the .NET 4.6 Framework.


The UIU Plug-ins 2.0 is a direct, compulsory upgrade for the UIU plug-in for MDT (v1.x). Support and UIU DAT files for UIU plug-in for MDT (v1.x) will be deprecated on Feb 1, 2018.

All OS deployment task sequences should be thoroughly assessed for remnants of the UIU Machine Configuration element, (associated with the UIU v1.x product), prior to uninstalling the UIU v1.x product. Failure to remove UIU v1.x task sequence elements prior to uninstallation will result in unrecoverable MMC errors when requesting properties on those task sequences, rendering those task sequences unusable!

Please refer to the UIU Plug-ins 2.0 - MDT User Guides for detailed implementation and usage instructions.

The UIU Plug-ins 2.0 is a versatile solution that may be invoked though the standard MDT Deployment Workbench interface via a task element (UIU Deployment Configuration) or directly through a Run Command Line task element. Furthermore, The UIU may be invoked manually from within a Windows PE session under the direction of UIU Support. Multiple modes of operation have been provided to accommodate environmental differences as well as policy/change control restrictions.

Microsoft Deployment Toolkit (MDT)
In MDT, integration consists of the inclusion of a uiusms.dll in the "C:\Program Files (x86)\Microsoft Deployment Toolkit\bin" directory as well as a modification (additional section appended) to the Actions.xml file in the same directory. If integration is not desired or permitted, an Administrator may launch the UIU Plug-ins 2.0 from a Run Command Line task element (with the correct arguments) to achieve a successful result.

For more information on alternative methods of invoking the UIU Plug-ins 2.0, Please contact UIU Support.

IMP Files

This version of the UIU requires the use of UIU IMP files to establish a UIU Repository from locally existing files. If bandwidth allows, Big Bang recommends that the UIU Repository be established (and regularly updated) from Big Bang's Online Updates resources. UIU DAT files are not supported.

UIU Import files (*.IMP) contain required driver files, driver database(s) and UIU components which are used to populate a UIU Repository from which deployed target machines will draw necessary files during OS deployment Task Sequence executions. These files are used in conjunction with the UIUPM.
