Prefetch Files

I have a very busy desktop machine with long program load times. I am always
pushing the 128 prefetch limit and as a result the oldest prefetch file in
my \Windows\prefetch is dated 9/19/2007. I have tried letting both Windows
and CCleaner maintain the prefetch files and neither does a good job. So
some questions follow:
1.) It looks to me that the Java prefetch files which are maintained in
their own \lib\cmm folder do not enter into the Windows prefetch
maintenance. Is this correct?
2.) Is there any way to increase the Windows 128 prefetch limit to something
like 256 with a cut to 128 when the 256 limit is reached? Or is there a way
to disable Windows prefetch maintenance completely?
3.) Do you think it would be worth maintaining the prefetch files manually
once a week? I can see at least 100 prefetch files that should be constantly
there. What are the RUNDLL32.EXE-xxxxxxxx.pf files?

That said, if you want to mess with this:

http://www.theeldergeek.com/prefetch_parameters_-_altering.htm

gives the few choices you can make with regard to this area--this involves
registry editing. Registry editing can render your system unbootable, and
Microsoft cannot support recovery from such a situation.

and, to turn it off:

I'd recommend reading Ed Bott's excellent information for the fun of it, and
resolving never to touch this stuff again.

Every physical or logical device is the end result of a long process of
design decisions. In the end, it is probably better to live with the
well-designed family car as it is, than to try to tweak it to emulate
Maserati performance.
