Could you give us an idea as to which applications give you the problem.
It's more than likely due to poor installers in those applications,
something that I've seen in the past. I used to have my partitions set so
that C: was a small boot parition that pretty much just had a DOS
installation and a boot manager. I'd then have various Windows installs on
D, E, F etc. On more than a few occasions an installer would (often without
prompting) start dropping stuff on C. Unfortunately your choices in this
situation come down to informing the softwares maker of the installer bug
and/or moving on to another piece of software.

I have found a reason for the problem. Checking the environmental
variables reveals that %systemroot% is set to "C" rather than "D" which
is the correct partition for the Vista OS.
I know that you can edit the individual environmental variables, but
don't know how to change the partition value that %systemroot%
retrieves. This may involve a registry or ini file change, but I don't
know the location from which %systemroot% retrieves this information.

For XP it's here:

HKLM\Software\Microsoft\WindowsNT\CurrentVersion

There should be a String value of SystemRoot, this is what you want.

It's also in HKLM\Software\Microsoft\Windows\CurrentVersion, so probably
want to change them both.

I will give it a try.

There is no HKLM SystemRoot entry in Vista's Registry that I can find with a
careful search.
Any other suggestions for finding the location from which %systemroot% is
read ?

Well, that could be the problem. I definately have one here...

HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion

SystemRoot - Type REG_SZ - Data 'C:\Windows'
