Why are there so many rundll32 processes with ClearMyTracksByProcess?

Occasionally my IntExp 11 under 64bit Win 7 is very, very slow or even blocked.
When I look into the TaskManager I find oftentimes lots of processes of type.

rundll32 for inetcpl ... ClearMyTracksProcess

See attached snapshot

I did not start these processes intentionally at least not manually.

They must be started automatically by IE itself or Windows or whatever.

Where do these process come from?

How do I force them to be faster executed?

Most of the time they run fast and close itself immediately.
Interestingly they seem not to run. The process load is 0

Thanks

I don't know why there are so many of these processes and I have never seen this. But i would tend to doubt they have anything to do with your problem. None show measurable CPU usage and none have CPU time over 5 seconds. And with memory usage at only 42% memory doesn't appear to be a problem.
