Microsoft Language Portal Blog:
We’ve launched a redesigned and enhanced Microsoft Language Portal!
What you're seeing on the Language Portal today is not only a redesigned and easier-to-use site, but part of a wider effort to provide IT terminology for public download in an industry-recognized format.
If you are a regular visitor to the Language Portal, you’ll still find our online terminology and UI strings search, style guide downloads, and UI string downloads for TechNet/MSDN subscribers, but we’ve also introduced a brand-new feature: public downloads of our international Terminology Collection—the key IT terminology we use across our products in more than 90 languages—in the industry-standard .tbx format.
