Latest version of the official Microsoft Windows Performance Toolkit designed for analysis of a wide range of performance problems including application start times, boot issues, deferred procedure calls and interrupt activity (DPCs and ISRs), system responsiveness issues, application resource usage, and interrupt storms.
WPT 4.1.1 does not support Windows 7. Windows 7 SDK comes with a version compatible with this OS release. Please obtain WPT from the Platform SDK if you plan on analyzing performance traces from Windows 7 systems.
The MSIs containing these tools are installed as part of the Win32 Development Tools portion of the Windows SDK. You can use the Web installer to install just the Win32 Development Tools portion of the Windows SDK.
