The Win7 RTM SDK is out, and with it the latest public version of Windows Performance Toolkit (which contains XPERF).

The SDK is huge but the lightest way to get WPT is to:

1)      Launch the installer from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=c17ba869-9671-4330-a63e-1fd44e0e2505&displaylang=en

a.       Note this is the “web” installer which only downloads the components that you choose to install

2)      Choose to install the Development Win32 Tools

3)      Find the wpt installer MSI’s (wpt_xxx) under C:\Program Files\Microsoft SDKs\Windows\v7.0\Bin
