Review Comment:
   Originally it was %x (hex integer) and %p (address in hex), I did the 
replacements by type not by file.
   On closer inspection it is due to the ingenius design from microsoft. This 
is an event handler if everything goes according to plan or an error number if 
its not.
   
   I think it would be okay to print it with the default both times, but I am 
not that familiar with CollectorInitiatedSubscription.

   > Event
   > 
   > A handle to the event. The event handle is only valid for the duration of 
the callback function. You can use this handle with any event log function that 
takes an event handle (for example, 
[EvtRender](https://learn.microsoft.com/en-us/windows/desktop/api/winevt/nf-winevt-evtrender)
 or 
[EvtFormatMessage](https://learn.microsoft.com/en-us/windows/desktop/api/winevt/nf-winevt-evtformatmessage)).
   > 
   > Do not call 
[EvtClose](https://learn.microsoft.com/en-us/windows/desktop/api/winevt/nf-winevt-evtclose)
 to close this handle; the service will close the handle when the callback 
returns.
   > 
   > If the Action parameter is EvtSubscribeActionError, cast Event to a DWORD 
to access the Win32 error code.
