Had this small problem today and I believe it would be interesting to share the solution. I was “forced” to update to Internet Explorer 8 (IE8) and for my surprise, VuGen crashes when trying to record anything with it.

You have to open the boot.ini file (C:\boot.ini) and add the following string to your boot line:
This is a very useful tip if you use PerfMon logs to monitor your applications.

Resample a log file, and then create a new log file that is based on specified counters, a time period, or a sampling interval.
For example, to convert a binary PerfMon log to a CSV file, use the command:
