Microsoft has called on American comedian Jerry Seinfeld to big up Vista in its next Windows ad campaign.

The software giant is keeping quiet on the details, even though world+dog have nicely spun out the firm’s plans over the past 24 hours.

According to the Wall Street Journal, Microsoft is spending $300m on the ad crusade to convince Vista-shy customers that the operating system really isn’t as crap as everyone says it is.

Funny man Seinfeld* is expected to reel in $10m from the ad deal. The campaign will centre on a theme around the slogan of “Windows, not Walls” and it will also feature Billy G. Microsoft will reportedly debut the ad on 4 September.

El Reg yesterday requested comment from Microsoft PR wonks. A flustered spokeswoman simply said something along the lines of “my people [London] need to speak to their people [Redmond]” about the “alleged” campaign. We're still waiting for a response. ®

*Is it just us or does Jezzer look more like an Apple Mac man to you?
