Microsoft to patch 17-year-old computer bug

A 17-year-old bug in Windows will be patched by Microsoft in its latest security update.
The February update for Windows will close the loophole that dates from the time of the DOS operating system.
First appearing in Windows NT 3.1, the vulnerability has been carried over into almost every version of Windows that has appeared since.
The monthly security update will also tackle a further 25 holes in Windows, five of which are rated as "critical".
