Microsoft has started showing the second in its series of Jerry Seinfeld/Bill Gates advertisements aimed at boosting interest in the Windows platform.

The television ads, which are part of a major marketing drive to highlight the benefits of Windows technologies, show the couple meeting, developing a bond and attempting to deal with normal people.

In the first ad, known as The Conquistador, Bill and Jerry meet for the first time and discuss the eponymous shoe of the title.

In the next ad, A Family Affair, the two are found living with a multi-generational family somewhere in America.

After struggling to integrate they are caught apparently pilfering a stuffed giraffe toy and are forced into manual labour - scrubbing what looks like a door.

They realise that it was a plot by the children to get them out, so they leave discussing the social connections that they had made.

Jerry applauds Bill for connecting so many people with his technologies and ponders what will come next: "Frog with an email, a goldfish with a web site, an amoeba with a blog? if it's yes, give me a sign." Bill complies.

The adverts are to continue, according to Microsoft. "Very soon, the campaign will turn toward communicating specifically about the Windows brand and the products that carry the Windows flag. Stay tuned," the company said.
