CMTrace Log Viewer is also refered to as the CMTrace tool (previously called the Trace32). It is a tool from Microsoft to view log files such as Microsoft Deployment Toolkit (MDT), Microsoft Software Center Configuration Manager (SCCM), DISM, and many others. Though, mostly for SCCM as it is part of “Configuration Manager Tools”. The Configuration Manager tools include client-based and server-based tools, and this will be discussed later on in this guide. Unlike many other log viewers, this tool shows the data as the log file is written or updated. The log file viewer shows the most recent updated lines written to log file and it is considered one of the favourite tool for MDT and SCCM administrators. Kindly refer to the following related guides: How to Add Packages to Windows image the DISM Tool, and how to add languages to Windows image using DISM and PowerShell. For WinPE-related guides, differences between MDT and WDS, and MDT deployment failed and Stuck at Command Prompt, and unable to determine destination disk, partition, and/or drive.
