Software Management

UEM Agent

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

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 v22.0.1 ISO has the latest WinPE 1.8.14 integrated. The latest PreOS packages are NOT automatically imported.

Further details and information about WinPE can be found here: WinPE

Common Changes/Enhancements


Update of Apache TomCat and Java components.

  • Apache Tomcat: 9.0.65 
  • Java:


With 22.0.1, the WakeOnLan (WOL) service has been extended in online and offline mode. The old functionality is still given and is read out. The extension is that the "Magic packet" is sent to all MAC addresses of existing network cards in the inventory. A "Directed Broadcast" is sent as soon as the IP address and subnet mask is known. We support the following scenarios:

  • No Inventory data available
  • All known MACs from NICs
  • Client DHCP Connection
  • Client DHCP Options
  • Static IP address

Patch Management

Patch Management now supports hybrid environment scenarios in which patches are not downloaded to the master server, but are available on sub depots. This functionality requires UEM Agent SFR 2209.1.2 or newer. More details are available as part of the agent documentation.

Enterprise Service Bus

The functions of the Enterprise Service Bus have been extended with version 22.0.1. The ESB deletes the variable configurations and Boot Configurations from the UUX and Empirum. 

The Enterprise Service Bus is now extended to send and receive messages. Therefore it is very important that all participants like Empirum, EgoSecure and Silverback use their own subscription / queue as described in the Service Bus configuration help. If they all use the same subscription / queue, messages will be consumed the fastest and may not reach the correct consumer.

Notification of extended maintenance period (LTSB)

Empirum version 21.0.3 is declared as LTSB version. Customers who are entitled to Matrix42 Premium Support thus receive an extended maintenance period beyond the release of version 23.0.0 at the end of April 2023.
