I had the same problem with WPA disappearing on startup. Tracked it down to a conflict between my installation of the ADK and SDKs. Specifically, Microsoft.Performance.Core4.Data.dll could not be loaded which I could see using fuslogvw.

The solution was to reinstall the Windows Performance Toolkit using the MSI in the ISO.

  1. Download the ISO from here: http://go.microsoft.com/fwlink/p/?LinkID=2033686
  2. Try repairing WPT by going to "[ISO Drive Mount]:\Installers\WPTx64-x86_en-us.msi", right clicking, and selecting Repair. This didn't work for me because I didn't have WTP installed, but it might for you so it's worth a try. If it doesn't work continue to the next step.
  3. Run the MSI mentioned above. This installed WPT for me and WPA was able to run again.
  4. If that doesn't work then try installing WPA from the Windows Store.


I had also tried uninstalling/reinstalling the SDK and repairing Visual Studio, but neither of those things worked.

My sources tell me that the conflict between various installers is being ironed out so this shouldn't be such a pain in the future.
