WMI Tracing

When you add the WMI package to your WinPE a problem that most people are unaware of us the default action of WMI in PE to create an in depth log file.  The real problem is that this file grows to be very large within a short period of time if WMI intensive applications are used.  Typically it grows to be about 16 MB in size before it stops logging.  This log file is then taking up precious space inside of the ram drive.  Thankfully its easy to toggle off this setting during the customization of your WIM.  After adding the WMI package change the following registry to the value shown:

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WBEM\Tracing\WMI] "SessionEnabled"=dword:00000000
