PR Week broke the story today that Edelman will handle the consumer launch of both products after beating out Waggener Edstrom and Weber Shandwick for the plum job.

The value of the account wasn't given but Microsoft's going to spend hundreds of millions marketing Vista and Office 2007 in what's likely to be its biggest product launch since 1995.

Waggener Edstrom remains the "agency of record" handling overall Windows and Office PR, company president, Frank Shaw, noted in the story.

"The appointment of another agency is to help with the consumer launch of the product Windows Vista and Office 2007 and is supplemental to the great work that is already going on,'' he said.
