This file grows at an incredible rate on this computer.  I booted up this morning at 7:30 AM, and now, 9 hours later, this file has exploded to 614mb.  The other day, after the computer had been up for about 6 days, this file had grown to 5gb!  It had consumed 75% of the available space on my C: drive.

I've observed that the file resets in size to 0kb every time I restart the computer.

One thing I tried was the utility Process Explorer from  It just informs me that the file is opened by "System".  That does not narrow this problem down much.

I am also unable to delete the file.  I get the error: "Cannot delete trace: It is being used by another person or program.  Close any programs that might be using the file and try again." whenever I try.

Why is this file growing so fast?  More importantly, how do I make it either: a) Not grow so fast, and/or b) Not get so big.  Is there some magic setting that is screwed up?

I bet stevenlewis meant to include a link on how to disable wmi logging.

In Win2K, it's controled by wmimgmt.msc.  I don't know if XP is the same or not.

Per chance did you download the MS boot optimizer? bootvis.exe?

If you did bootvis.exe has to run twice.  The first time it turns logging on, then you reboot and it will analyze trace.log
I have heard that bootvis.exe crashes a lot and thus creates the problem of not turning the log off.  
All you have to do is select 'stop logging' from the trace menu in bootvis.exe (to stop the logging)
WMI has no control over this particular log.

Yes, this is exactly what happened.

You see, several months ago, I ran that utility and it crapped out on me (read: locked up) before it finished.  Not knowing anything, I just deleted it and didn't think anything of it.

I downloaded the utility again, tried it again, and it worked fine (though it only improved the computer start time by about 5 seconds).  No more trace.log!
