It's a pretty strange design.
The evidence suggests:
1) There isn't a separate service generating the journal. It is like
it is generated by NTFS.sys itself. And this makes sense, when you
consider that it needs to log every burp and fart involving files
or directories. While they could have made it a separate service,
made it a filter driver and put it in the file stack, that just
creates a programmatic mess for people like AV program designers,
when they need to hook the file system and watch their own burps
and farts. Better to make it invisible. Only problem is, not
putting enough controls in the Registry for it.
2) FSutil can delete the journal. Any journal-dependent program
(such as FRS, or a file search program) can request a new one
be created. You can set a space allocation for the thing, but
the documentation suggests the lower limit is not zero. So it
might ignore attempts, or error out, on a setting of zero. I'm
not going to try that right now.
You could go around, uninstalling or disabling all file search
code. Or, every time you find the journal running again,
consider what program you just used, and delete that. But
that's surely a route to madness.
You can switch over to ExFAT for C:. If you have a second
OS installed on the machine, it should be relatively easy to
Robocopy the files off, reformat, and move them back. As long
as "fixboot" knows how to put back a partition boot sector
onto an ExFAT partition, that is.
Wikipedia says this update adds ExFAT to WinXP. But that's
not going to modify the copy of Fixboot on my WinXP installer CD.
So I don't know what happens there. I feel you'll need Fixboot,
as once you format C: with ExFAT, the file system header is blown
away, and with it, the partition boot sector.

I regularly move the files off C:, reformat C: to FAT32,
then move the files back, all using Robocopy. And a Fixboot
is necessary as the final step, if I expect WinXP to boot
again. The OS in question, is the one I'm typing on right
now. I feel I could attempt to do that with ExFAT, except
for the details of Fixboot. Perhaps I'd need Vista/Win7/Win8
tools to do it ?
