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.

By default, the OneTrace application is installed at "C:\Program Files (x86)\Configuration Manager Support Center\CMPowerLogViewer.exe.


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.
