Thanks for being clear about this part! Unfortunately, there are a few
other parts that aren't clear yet, so hopefully you can expand on your
question a bit.

Tip: Try adding "print(raw_wql)" just underneath this line, to see if
you're getting back what you really want. The backslash at the end of
ValueName is not currently doing anything.
>>watcher = c.watch_for(raw_wql=raw_wql,wmi_class = "__ExtrinsicEvent")
>> process_created = watcher()
This code isn't complete. Can you post a complete (and minimal)
example piece of code?

It'd help hugely if you could post the entire traceback here - what
exception you're getting, and the exact lines that produce it.

Just for reference, this is a general Python discussion list. Lots of
us won't know specific libraries, so all we can offer is fairly
general information. If you can't get the help you need here, you may
do better to look for more specific help about this module.
All the best!
