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

August 10, 2021 - RELEASE
Includes UIU plug-in for SCCM version
Includes UIUPrep version
This is an update of the UIUPM application for SCCM & MDT ONLY.

New Feature: Advanced Repository Management


The Advanced Repository Management feature, (combined with a compatible version of UIUPREP.exe), allows the Administrator to enumerate multiple UIU Repository locations in a task sequence without exposing the credentials required to access those shares or packages, thereby making the process more secure.

When would this be useful or necessary?
  1. MDT - The environment has more than one UIU Repository established to service MDT task sequences in the environment. This may be useful in maintaining test environments alongside a production environment.
  2. SCCM - The environment has more than one UIU Repository established to service SCCM task sequences in the environment. This may be useful in maintaining test environments alongside a production environment.
    • Multiple UIU Repository packages in the environment for testing vs. production.
    • Distribution point timeouts, typically resulting in failure to complete synchronization.
    • In instances where it is desirable to establish network shares outside of SCCM due to slow WAN links or the like. This method bypasses the standard SCCM distribution process and can make the updating of UIU Responsories more efficient, minimizing the time required to update the UIU product and execute a task sequence.

UIU Support strongly recommends that Administrators review this entire section prior to implementing this feature.

UIU Support strongly encourages Administrators who wish to utilize the features of Advanced Repository Management to consult with UIU Support to ensure a seamless and effective deployment environment.

Reminder: New Feature (UIUPREP): Force consideration of distribution points in NOMAD-enabled deployments

Added a "-smsforceclr" switch which may be included in the UIU task element under the options tab in order to allow NOMAD-enabled deployments to consider distribution point package shares in addition to NOMAD cache locations. This only affects NOMAD-enabled deployments.

Reminder: Updated Feature (UIUPREP): Package path behavior change

Added a "-packagepath "\\path\one, \\path\two, \\path\three"" switch which may be included in the UIU task element under the options tab in order to allow UIUPREP to use the existing SCCM network access account to access package path locations without requiring the "-networkresource" switch. Customers using the "-packagepath" switch no longer are required to use the "-networkresource" switch in order to access UIU package path locations if those locations have been configured to allow the SCCM network access account default access to those locations. This should eliminate the use of the cumbersome "-networkresource" switch when supplementing customer-maintained UIU repository locations in addition to SCCM distribution point locations. For more information, please contact UIU Support.

Known Issue: Command Line Interface Updating issue

When using the CLI feature of the UIUPM application to perform updates against a repository, the updates may not complete fully.

Development to alleviate this issue is ongoing.

Known Issue: UIU integration with SCCM Provider-Independent Sites

UIUPM behavior will stall at "Refreshing" when selecting the Microsoft System Center Configuration Manager option under the Microsoft menu.


On a dedicated Provider, the operations framework is not installed when performing an install operation.

These instances currently require a manual installation process. Contact UIU Support for details. Development for a resolution is ongoing.

Reminder: "HTTPS ONLY" (Native Mode) Support

When SCCM has been configured to utilize "HTTPS ONLY" (Native Mode), the UIUPREP application running in WinPE fails to locate a UIU Repository Package with the UIU Deployment Configuration task sequence element configured for UIU Hybrid OS deployments.

Support for "HTTPS ONLY" (Native Mode) when using UIU Hybrid OS deployment configuration has been added. This solution requires UIUPREP.EXE v5.10.0.0 or newer. Please contact UIU Support for more information.

Technical Note: Big Bang does not recommend utilizing "HTTPS ONLY" as it encumbers OSD with additional layers of complexity without providing significant security benefits. Sufficient security is realized when using HTTP/HTTPS Mixed mode.

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 ≥

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

The UIU Plug-ins 2.0 for SCCM version (or newer) also includes support for 1E Nomad/Active Efficiency. Please contact UIU Support for details.

The UIU Plug-ins 2.0 is a versatile solution that may be invoked though the standard SCCM Console 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.

System Center Configuration Manager (SCCM)
In SCCM, integration consists of the inclusion of a uiusms.dll in the "C:\Program Files (x86)\Microsoft Configuration Manager\AdminConsole\bin" directory as well as the addition of necessary WMI classes (MOF) to support the UIU Plug-ins 2.0. 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. Furthermore, if an Administrator is not able to control the configuration of various SCCM Remote Console implementations (distribution of a single UIU dll file), the integration of the UIU Plug-ins 2.0 may prove to be problematic and utilizing the Run Command Line task element will alleviate those issues.

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.
