Currently this is only implemented on Windows. See crbug.com/424024 for background on why it was added. Args: proc: a process object returned from subprocess.Popen. app_name: on Windows, is the prefix of the application's window class name that should be searched for.

On systems with multiple CPUs, this function may run on any CPU. Args: msr_number: The number of the register to read. start: The least significant bit to read, zero-indexed.
