Some news reports have suggested that Microsoft is about to issue Vista Service Pack 1.
With many firms waiting for the service pack to come out before buying the current OS, Microsoft is keen to convince them to buy now, instead of holding out for a couple of weeks for SP1.
The company is already working on the next version of Windows, previously codenamed "Vienna". It is now reported that the internal development name for the next version of Windows is "7".
It took Microsoft five years to develop and introduce Vista, and the company is aiming to radically reduce the time it takes to introduce '7'.
