6x13
I've used the same version of 6x13 on Windows (http://www.hassings.dk/lars/fonts.html) since forever, pretty much, and before that I used some other version of 6x13. Today, 15 years since I first set eyes on it, it's still my console font and my emacs font.
Unfortunately, modern versions of Visual Studio don't support bitmap fonts, so for that I've had to change to 9 point MS Gothic. This has one unusual feature ('\' appears as a yen symbol, since it's a Japanese font), and the descenders are rather short (presumably Japanese readers are differently sensitive to this stuff), but it's tall like 6x13, pixel-perfect at 9 point size, and perfectly serviceable for programming work.
(There's also a serif equivalent, MS Mincho, which is usable but a bit fussy for my taste. 8 point Gungsuh Che and Gulim Che are also workable, but I found them a bit fussy too. I think they are Korean or Chinese.)
