The Microsoft Bing team is currently offering Bing-branded Talking Rain carbonated beverages in cans in refrigerators on the Redmond campus, trying to increase awareness and usage of the search engine among employees, hoping that they’ll then help “evangelize” Bing to outsiders.

Bing stickers are also popular fixtures on Microsoft laptops.

Three years ago, it was Windows Vista Talking Rain in the Microsoft refrigerators, but employees aren’t likely to see a Windows 7 soda, company insiders say.

The Windows team, under no-nonsense divisional president Steven Sinofsky, is focusing its marketing dollars for the Oct. 22 product launch more on external audiences — the people who actually pay to use the operating system.

No word yet on whether the Bing soda is better than the Windows Vista soda was. But based on early reviews, at least, the new Windows software shouldn’t have nearly the bad aftertaste that the last one did.
