It may help to narrow things down if you could perform some basic tests.
For example, if you have access to a color calibration file (basically a
chart that prints scales and a gamut wheel) and reference print, you can
see whether the printer is reproducing that chart correctly. If you have
a colorimeter, you can measure the printed output and compare that with
what you see on the screen, understanding that the CMYK+ gamut will have
some differences from the RGB gamut.

Some settings seem to be more or less right as far as color is
concerned, but that is not my present concern. It's the fact that
changes in settings cause changes in color in ways I do not
understand.

Can you give some specifics? What settings? What kinds of changes do you
see?

Basically changes in hue and saturation.

Different color space settings will result in different color gamuts in
a print, which is to be expected.

Yep. What is Windows doing in this respect?

Nothing new, AFAICT. I hope you're not expecting an OS to make all color
spaces look the same in print. That would only happen for a very narrow
range of colors and intensities.

It's doing something new since Vista. That's where all kinds of bells
and whistles were added and I can find nothing which tells me how it
works.

I'm not seeing any of these issues on my systems, so I can only hope
that you find out what is going on with yours.

Are you printing with more than one color space? I mean 'color space',
not just printer profile.

Yes, I do use color spaces dependent on the type of job. My work also
requires me to calibrate my proofing printers to match the final output
devices, so "standard" printer profiles aren't of much use to me.
