Microsoft unveils patch package

The security update contains six patches which close 15 vulnerabilities found in a variety of Windows programs.
The patches help to shut loopholes in Internet Explorer, Outlook Express, Windows Mail and Windows Vista.
More than half the loopholes are rated as "critical" which often means they can be exploited without a PC owner's knowledge or consent.
Vista, the latest edition of Microsoft's operating system, gets a patch for itself which aims to stop malicious hackers exploiting a loophole to steal administrative passwords
