Windows 7 - delete temp files rundll32.exe not responding

deleting temp files doesn't quit running.  Turning off Win XP causes several
apps to end--except rundll32.exe.  I get message it is not responding. I
click on ending it.
I can restart ok.  Same thing happens again. I can find the file doing a
search.  If the file is messed up--how do I replace it?

HiAndrew, Thanks for your reply.  My problem was that I could not run disk
cleanup.   It would not quit and locked up keyboard etc.
Aolved the problem by downloading and running ccleaner.  Only then woudl
disk cleanup run.

Hi, Thanks for your reply and help.  What finally worked was running
ccleaner.  I can't believe it removed 1,507.5 MB of stuff.  Took 6923
seconds.  I was in the habit of deleting history and cookies, etc every week
or so.  It puzzles me where ccleaner found all the stuff to delete.
