How do I typeset equations in Word as pretty as LaTeX does?

Question

This might be the N+1 th question about how to put vector graphics and/or equations in MS Word, but none of the solutions I found on the net satisfy me.

My ultimate goal is to be able to embed Latex equations into a MS Word 2013 document, because I'm stuck to a Word template I need to use, and because Word's equations look ugly. It's already lame to resort to "insert->image" every time I need an equation, but it seems that I don't have much choice. What I've tried:

• Because I use Word 2013, I can't use TexPoint

• MS Word equations look terrible compared to Latex.
  in Word:

  in Latex:

• Converting my pdf into .ps or .eps directly (either via pdf2ps, via Illustrator, or Acrobat), results in a completely messed up result, once in Word:
  without embedding fonts:

  with font embedding:
  (note that this is not ok, the integral lines are distorted, the 1 is ugly...)

  with font embedding, but just another equation:
  (note that all the latex fonts used are in my Windows\Fonts directory anyway)

• Converting the equations into vector graphics (i.e., in Illustrator, Types->Create Outlines) , there should be no font problem, but the result still looks bad once in Word (in Illustrator and other programs, it always look good) :
  

• Same as above, but converting to wmf, it's almost ok, but some characters are still distorted:

• Same as above, but converting to emf, it's even better, but still, the B of the second equation is also destroyed:

when I export into PDF, it's degraded a bit, albeit near ok.

I know that once exported to PDF, the rendering of Word vector graphics are supposed to look better, but they really do not in general.

Of course, I do not want a solution which rasterizes the images: that's not the point of vector graphics, the solution is bad and should not be used, and it can significantly increase the output size: Here, Eq 1 is rasterized, inserted in Word and exported in a PDF using Word's pdf exporter (with all high quality options, and it looks similar with other pdf exporter such as Nitro or Adobe pdf):
It obviously looks... rasterized and blurry. The file size has increased to 200 KB (no, I do not have a single equation, and Nitro once managed to output a 300 MB pdf with all my rasterized equations which still looked blurry).

I'm ready to give up and use the best of the solutions above (Vectorized and exported in EMF), but I'd like to know if a better option exists at all.

If you have an option which just allows for using Word's equation editor, and change the font to use Latex's symbols, I'd also be extremely happy.

[[EDIT: Jukka K. Korpela's answer is almost what I am looking for. Unfortunately, when I use this solution and export to PDF using Word, I get:

If I further constrain the PDF to be PDF/A compliant (which I'd ideally need), the result is even worse:
where I have put some context around the equation: the line of text above the equation is half cleared. If I print to PDF instead, the rendering is ok, but I loose all the links in my document, so that's not an option. ]]

Using the tools in tab DESIGN in EQUATION TOOLS, you can produce a large integral symbol, as shown below. It is very different from the rendering you get if you just enter the INTEGRAL character “∫”.

You can change the font of equations by selecting text in them and using the font menu in the HOME tab. However, Word lets you use only a limited set of fonts. It seems that the font names must end with the word “Math”. (If you set font to something else, it just does not take effect; the text stays in the font used before the attempt to change it.) In the image below, the first version uses Cambria Math, the default, while the second version has its font set to XITS Math, which somewhat resembles the font you are using in LaTeX.

The default font used in equations can be set in the equation mode preferences. To enter them, click on the small icon in the lower right corner of to “Tools” block in EQUATION TOOLS, tab DESIGN. The setting affects only new equations
