Microsoft's new Windows Vista operating system, expected in 2007, is reportedly able to adapt itself to the hardware of any computer it is installed on.

This means fairly basic minimum set-up requirements as an 800 MHz processor and 512 MB of working memory and a graphic card with DirectX 9 support are perfectly adequate, Computerwoche magazine reported.

But more computing power opens up many more security and system set-up possibilities, as to get the most out of Vista would require at least a one GHz processor, the report said.

There should also be at least one GB of working memory and a 40 GB hard drive with 15 GB free.
