Microsoft responded in a blog post by Executive Vice President Terry Myerson explaining the existing options for upgrades and also revealing that, starting next year, Windows 10 would be installed on Windows 7 and Windows 8.1 through the normal update process.

Facebook is blocking any link to Tsu.co on every platform it owns, including Messenger and Instagram. It even went back and deleted more than 1 million Facebook posts that ever mentioned Tsu.co, making pictures, videos and comments disappear in an instant.

"We're persona non grata," said Sebastian Sobczak, who founded Tsu. "You can type in all sorts of seedy websites, and you can get to them. But not us. We don't exist."

Facebook says it will unblock Tsu if it changes just one thing: Tsu users shouldn't be able to simultaneously post to Tsu and Facebook.

"The TPP means that America will write the rules of the road in the 21st century," Obama said. "If we don't pass this agreement—if America doesn't write those rules—then countries like China will.

Meanwhile, the deal also exports US copyright law regarding how long a copyright lasts. The plan, which now needs approval from all the pact's member nations, makes copyrights last for the life of the creator plus 70 years after death.

Motion Picture Association of America Chairman Chris Dodd lauds the partnership, saying: "Enacting a high-standard TPP with strong copyright protections is an economic priority for the American motion picture and television industry, which registered nearly $16 billion in exports in 2013 and supports nearly two million jobs throughout all fifty states."

While FBI officials are America’s servants, Baker argued that encryption is making it harder for the bureau to protect the nation from terrorism and other criminal activity.

“Your Gmail operates the way it does because Google can monetize the communications,” he said. “You could pay for a service that doesn’t operate that way, but most people don’t tend to… Are we really going dark or are we living in a golden age of surveillance?”

Candy Crush describes itself as the "sweetest game around" - but even so there's no guarantee that the $5.9bn (£3.8bn) takeover of King.com won't leave both investors and players with a bitter taste.

Candy Crush Saga, which was first launched on Facebook and smartphones in 2012, caught the public imagination and still makes up about a third of the company's revenue.

Even though the company has produced more than 200 games, including the popular Bubble Witch and Farm Heroes, it has yet to repeat the success it found with Candy Crush Saga.

Estimates suggest that emissions on the road could have been 40 times worse than in the testing environment.

A new notice posted this morning on the EPA's Web site and sent to Volkswagen includes vehicles using the larger 3-liter V-6 TDI engine. The notice lists those vehicles as the "VW Touareg," "Porsche Cayenne," "Audi A6 Quattro, A7 Quattro, A8, A8L, and Q5."

He said keeping web browsing data was not for spying on the public but to see "for example, whether a suspect has downloaded a terrorist manual".

The minister for internet safety and security, Baroness Shields, had said she recognised the "essential role" that strong encryption played in protecting people's details.

But she added the government still wanted tech companies to be able to unscramble "targeted" data and hand it over when required.

In older versions of Windows, uninstalling a program wasn't all that straightforward -- you had to go through the Programs and Features menu in the Control Panel. But in Windows 10, uninstalling a program (either a desktop program or a Windows 10 app) is much simpler.

Microsoft will automatically download Windows 10 to millions more PCs in a "recommended" Windows update early next year.

Then early next year, Windows 10 will become a free "recommended" update – meaning it will be immediately downloaded by any PC or device that automatically installs "important" and "recommended" updates.

The Facebook CEO repeated that ambition during a town hall meeting Wednesday at the Indian Institute of Technology in New Delhi. Zuckerberg told the audience of students and professionals that the social network's mission is to make the Internet accessible to the entire world, them included.

"The people who are not yet on the Internet can't sign an online petition pushing for increased access to the Internet," he said. "We all have a moral responsibility to look out for people who don't have the Internet, and make sure that the rules that benefit us, don't get twisted for people who don't have a voice."
