Internet Explorer: Microsoft plans 'silent' updates


From January, Internet Explorer (IE) users will be automatically updated to the latest version of the browser.

Microsoft said it was starting the project to update millions of machines to improve security online.
Future updates to the browser would be applied without a user's knowledge to help beat scammers catching people out with fake updates.
Those who did not want their browser updated could opt out or uninstall the software, said Microsoft.
"The Web overall is better - and safer - when more people run the most up-to-date browser," wrote Ryan Gavin, Microsoft's IE boss, in a blogpost explaining the plan.
He said the data gathered by Microsoft for its security intelligence reports showed that many cyber criminals targeted old or outdated software when they tried to trick people into installing fake updates.
To beat such scams, Mr Gavin, said that once the latest version of the browser was installed all future updates would arrive silently and be applied without a user getting involved.
Chester Wisniewski, senior security advisor at Sophos, said the plan would aid those who did not see the importance of staying up to date.
"Microsoft has been struggling with browser stragglers for years," he said in a statement.
Demise of IE6
The giant upgrade programme will affect IE users running Windows XP, Vista and 7, and will first be rolled out in Australia and Brazil. Only those Windows users with automatic updates turned on will be enrolled in the programme.
Those using Windows XP will be upgraded to IE8, while those on Vista and 7 get bumped up to IE9. This will probably mean the demise of IE6, a 10-year-old version of the browser that Microsoft has been trying to kill off for a while.
Figures gathered by Microsoft suggest IE6 is used by about 8.3% of people around the world, with the biggest number of users in China, where almost 28% of people remain wedded to it.
Globally, Internet Explorer is still the most popular browser, with more than 52% of people using it, according to net market research firm Net Applications. Mozilla's Firefox and Google's Chrome are battling it out for second place.
Microsoft said it had made tools that would let people avoid or uninstall the more up-to-date versions of the browsers if they wanted to stay with an older copy.

Self-cleaning cotton nanoparticle coating invented

Efforts to create self-cleaning cotton fabrics are bearing fruit in China.

Engineers have created a chemical coating that causes cotton materials to clean themselves of stains and remove odours when exposed to sunlight.
The researchers say the treatment is cheap, non-toxic and ecologically friendly.
Retail experts say the innovation could prove a hit with retailers thanks to a growing demand for "functional clothing".
The research was carried out by engineers at Shanghai Jiao Tong University and Hubei University for Nationalities, and is published in the latest issue of the Applied Materials and Interfaces journal.
The study focuses on titanium dioxide - a chemical known to be an "excellent catalyst in the degradation of organic pollutants".
The substance is already used in self-cleaning windows, odour-free socks and stay-clean kitchen and bathroom tiles.
Initial efforts to extend its use to cotton fabrics proved limiting because the substance's self-cleaning properties could only be "excited" under ultraviolet lights, making it impractical for everyday use.
Creating the coating
The team's breakthrough was to create a nanoparticle alcohol-based compound made up of titanium dioxide and nitrogen.
The mixture was added to triethylamine, an acid neutraliser commonly used in dyes. After being stirred for a 12 hours at room temperature, the liquid was heated at 100C (212F) for a further six hours.
The cotton fabrics were then immersed in the mixture before being squeezed dry, heated and immersed in hot clean water.
Finally the coated materials were treated with silver iodide particles, which aid light-based reactions.
To test the effectiveness of their invention, the engineers marked the fabrics with an orange dye stain and exposed them to the sun. After two hours in the light, the team said 71% of the stain had been removed - a "dramatic" improvement over previously trialled techniques.
Long-lasting
The experiment was repeated on the same cloth five times with no loss of activity - suggesting that the enhancement was stable. Washing and drying the material did not reduce its effectiveness.
Clothes industry experts said there should be huge interest in the process if it could be rolled-out on an industrial scale.
"This kind of functional clothing has already proved very popular, especially in Japan where the authorities ordered a crackdown on air conditioning use after March's earthquake caused power shortages," said Isabelle Cavill, a clothing analyst at Planet Retail.
"It is also likely to prove popular in other parts of Asia where the heat causes sweat problems."
Ms Cavill noted that the Japanese retailer Uniqlo has started promoting a "Silky Dry" range of clothing that promises to keep skin dry and odour-free thanks to special "high-tech processing neutralisers".
The firm also markets a "Heattech" line which "creates heat" to keep users warm.
Meanwhile, scientists at the University of Sheffield have been researching a fabric conditioner that helps purify the air around people wearing treated clothes.
"The main retailers to pick up on this latest innovation are likely to be those selling basicware," said Ms Cavill.
"In the West that could mean Wal-Mart or Marks and Spencer would want to invest in the Chinese technology to take advantage of functional clothing becoming more popular with shoppers."
