I wanted to ask where you are filtering the powershell wouldn't you want to leave that in case someone tried to run scripts via powershell?

This is blacklisting events for powershell that is run from the path "[C-F]:\Program Files\SplunkUniversalForwarder\bin" which would be scripts run by Splunk UF.

edit: changed drive letter to match regex C-F
