Intel is refusing to adopt Windows Vista as its OS of choice across the company, according to reports.

A member of staff at Intel told the New York Times that the company's IT staff "just found no compelling case for adopting Vista".

However, an Intel spokesman told the newspaper that while Vista was not being deployed across the board, parts of the company are upgrading to Microsoft's latest OS.

The revelation will come as a blow to Microsoft, which was once so close to Intel that the two companies were described as 'Wintel'.
