  • Ability to enable filters without leaving the log view
  • Scrollbar hints to quickly identify clusters of errors
  • Fast log opening for large files

OneTrace works with many types of log files, such as:

  • Configuration Manager client logs
  • Configuration Manager server logs
  • Status messages
  • Windows Update ETW log file on Windows 10
  • Windows Update log file on Windows 7 & Windows 8.1


  • .NET Framework version 4.6 or later


OneTrace installs with Support Center. Find the Support Center installer on the site server at the following path: cd.latest\SMSSETUP\Tools\SupportCenter\SupportCenterInstaller.msi.


Support Center and OneTrace use Windows Presentation Foundation (WPF). This component isn't available in Windows PE. Continue to use CMTrace in boot images with task sequence deployments.
