Is there a way to turn off WMI logging?

[Guest wsxedcrfv]

Is there a way to stop the useless creation of .XML files in the \WINDOWS\PCHealth\HelpCtr\DataColl\ directory?

I understand this has got something to do with either WBEM or WMI - can someone explain the *difference* between WMI and WBEM?

There are also log files created in \system32\wbem\Logs, but I've found instructions on how to stop that.

Bonus question: I would like to turn off WMI and WBEM completely. I come across lots of dire warnings about turning off the WMI service (or services?) but none of them explain exactly what system functionality depends on them. If anyone can answer that, please do.
