how to find the process about pywintrace

[abergl]

1. Use the --logfile command line argument.
2. The description coming from the event may or may not convert to UTF-8 properly. This is one of the reasons that we used bytes.
3. The ProcessId field in the event header contains the process PID.

    guid = {'Some provider': etw.GUID("{1C95126E-7EEA-49A9-A3FE-A378B03DDB4D}")}
    job = etw.ETW(guid)
