Empirum 21.0 Update 3 - Release and Update Notes

About This Document

This document describes functional changes, bug fixes, known issues, modified behaviors and changed platform support that have been added since the last update. 

Please find the installation files of this version on Matrix42 Marketplace

System requirements, integration guides and instructions for installation and update are available in the Matrix42 Help Center

Software Management

Extended distribution flags and package properties

With Empirum v21 Update 3 a new distribution flag called "Optional" has been introduced. The flag can be used to "accounce" new packages in order to allow the end-users to already install them without being forced (e.g. Windows Feature Upgrade) or to create a new type of kiosk by assignment. More details about this new feature can be found in the documentation.

Also with release another package property was introduced to show end-users if a package requires a reboot or not. It can be defined in section "misc" and will be shown on the UEM Agent whenever an installation is scheduled.

UEM Agent

The latest agent with all details and information about the new features can be found here: Matrix42 Marketplace


Inventory is now able to detect the edition of Microsoft PowerBI Report Server.

OS Installer

If you use only WinPE and no longer EPE to install your operating systems, you can delete all imported WADK and WAIK (Configuration > OS Installer > Import) permanently.

Old or unneeded PreOS packages should be deleted from the EMC and locally from the hard disk.  

Please check here in the EMC in the tab Configuration - Software Management - Depot - Matrix42 PreOS Packages and delete all unneeded PreOS packages.

Locally you can delete the same PreOS packages from the hard disk in the directory "%EmpirumServer%\Configurator$\PackageStore\PreOSPackages".

The latest WinPE with all details and information about the new features can be found here: Matrix42 Marketplace

Since Empirum version 21.0 Update 2, the WinPE driver assistant is the only option in the EMC for configuring Windows drivers. With Update 3, the following additional features have been integrated:

  • Windows 11 & Windows Server 2022 support
  • Filter for Vendor, Model and driver
  • Description field per driver model
  • the option to export drivers and delete drivers from the database
  • the option to replace or extend a Drivers.json file

You can find more detailed information in our Matrix42 Help Center

Support of Windows 11 and Windows Server 2022

The driver wizard, as well as the creation of offline boot media, also supports Windows 11 and Windows Server 2022 sources with Update 3.

To install Windows 11 successfully, the computer must meet the following requirements:

  • TPM 2.0 must be enabled
  • Intel 7th Gen processors

Common Changes/Enhancements


We had a very low risk by using Log4j in version 1.2.16. Nevertheless, the version has been updated to 2.17.1 There is also a new Java version (17.0.1) and a new Tomcat version (9.0.56).

Packaging Center

With the update 3 there is a new tile in the Packaging Center. The Offline PXE Image Creator is used to create a PXE boot image locally on each machine which can then be uploaded and imported via SDK or as a zip file via UUX. Afterwards it can be assigned as usual in the EMC. The tool itself is a Power Shell based application, with which you have all known options to choose from, which you know from the EMC boot configuration.

In addition to the new tile in the Packaging Center, there is also a new software package to import. The Matrix42 WinPE Support Package 1.8.11 is required on the end device to create a PXE image.

Restriction to UEFI x64 exists for the created PXE boot images

You can find more detailed information in our Matrix42 Empirum Online Help.


The following operating systems have been removed (OS-Installer - Import) and are no longer supported:

  • WinPE
  • Windows Vista and XP
  • Windows Server 2003, 2003 R2, 2008 and 2008 R2
  • Apple

For security reasons, a backup of the "PrePackages" folder has been created. This is located under %Empirum%\Configurator\PrePackages.old

In the OS Installer - Operating System Configuration section, all Windows specific operating systems have been removed. These configurations are only required for EPE installations and are therefore no longer needed. With the upcoming major release 22.0 further no longer supported and required areas will be removed from EMC. 

Notification of extended maintenance period (LTSB)

Empirum version 19.0.3 is declared as LTSB version. Customers who are entitled to Matrix42 Premium Support thus receive an extended maintenance period beyond the release of version 21.0.0 at the end of April 2021.
