I've came across many blog or forum posts where people say they like the Microsoft Windows Vista fonts and use them in Linux. I don't find anything special with any of those fonts but maybe you do. If so, read on!
I can't legally put these fonts for download here, but I found a script which extracts the Windows Vista fonts from PowerPointViewer.exe, directly from the Microsoft website.
To download (extract) all the Windows Vista fonts and install them in Linux, simply run the following commands in a terminal:
wget http://plasmasturm.org/code/vistafonts-installer/vistafonts-installer chmod +x vistafonts-installer ./vistafonts-installer
Of course, before running the script, you may want to take a look at the code.
Among the fonts the above scripts installs are: Calibri and Consolas but not the Segoe UI font. If you really want the Segoe UI Vista font too, download this Vista transformation pack, extract it and you'll find Segoe UI under vista > font.
