Windows Performance Toolkit Technical Reference

Included in the Windows Assessment and Deployment Kit, the Windows Performance Toolkit consists of performance monitoring tools that produce in-depth performance profiles of Windows operating systems and applications. This documentation discusses both Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA).

Windows Performance Xperf Command-Line

The Windows Performance Toolkit consists of two independent tools: Windows Performance Recorder (WPR) and Windows Performance Analyzer (WPA). In addition, support is maintained for the previous command-line tool, Xperf. However, Xperfview is no longer supported. All recordings must be opened and analyzed by using WPA.

The following are the system requirements for running Windows Performance Toolkit:

  • Windows Performance Recorder (WPR): Windows 8 or later.

  • Windows Performance Analyzer (WPA): Windows 8 or later with the Microsoft .NET Framework 4.5 or later.

You can download the Windows Performance Toolkit by visiting the Windows Assessment and Deployment Kit site.
