Reduce Windows 2008 Event 4624

Hi all,

i have a problem with the extra (useless) information of log produced by Windows 2008. Especially this event (4624), it almost eat my licensing space. If i could remove the blue part, thus saving half the space, i'll save many GB/24h of useful space (my siem environment is really huge).

We send those events to Netwitness with WinRM. I can't use Snare agent on those machines (and i can't, ofc, change Windows Version ;-) ).

Are there other ways i can remove this lines from the log (directly on windows 2008 machines, of directly on SIEM), since they do not provide useful information and they only waste license space ? if this could be done, i'll save half the space (from 2kB log, it will become 1kB log)

Tyvm, and sorry for my bad english ;-) i hope i managed to explain clearly the problem.
