Symptoms

You experience a decrease in performance when you use an evaluation runtime that is created by using one of the following editions of Windows Embedded Standard 2009:

  • Windows Embedded Standard 2009 Evaluation Edition

  • Windows Embedded Standard 2009 Academic Edition

  • Windows Embedded Standard 2009 Retail Edition

    Note Runtimes that are created by using Windows Embedded Standard 2009 Retail Edition are built without a Retail Product Identification (PID). Therefore, the runtime functions as an evaluation runtime.

For example, you may see CPU usage increases of 50% to 100% when you experience this issue. This performance decrease is most noticeable when the runtime is running on a minimal hardware configuration.

Cause

This problem occurs because there are multiple calls to the WPAbaln.exe application, and the application starts multiple processes.
