Microsoft has admitted that speech recognition features in Vista could be hijacked so that a PC tells itself to delete files or folders.

Vista can respond to vocal commands and concern has been raised about malicious audio on websites or sent via e-mail.

In one scenario outlined by users an MP3 file of voice instructions was used to tell the PC to delete documents.

Microsoft said the exploit was "technically possible" but there was no need to worry.

Chip maker Intel have pushed the bounderies of chip making by announcing that they will be starting manufacturing of processors using transistors just 45 nanometres wide. Previously anything smaller than the current standard of 65nm had issues with performance due to current leaking. However using high-k metals, a sort of substitute for silicon, this issue was solved. With a substitute found chances are processors are about to get a lot faster.
