Jerry Seinfeld will be one of the key celebrity pitchmen in Microsoft Corp.'s $300 million advertising campaign aimed at changing its image, The Wall Street Journal said on Thursday, citing people close to the situation.

Seinfeld, known for his eponymous television sit-com, will appear in ads with Microsoft Chairman Bill Gates and will receive about $10 million for the work, the report said.

The attempted image overhaul comes in the wake of Apple's "Mac vs. PC" ads, which feature a nerdy PC guy getting upstaged by a hip Mac counterpart.

The new ads, likely to debut on September 4, is expected to use some variation of the slogan "Windows, Not Walls", the paper said.

For its new campaign, Microsoft also considered a range of other famous personalities, including comedians Will Ferrell and Chris Rock, the paper said, citing people familiar with the matter.

Microsoft was not immediately available for comment.
