Microsoft, Windows 8 | featured news

Valve head—and one-time Microsoft employee—Gabe Newell has branded Windows 8 "a catastrophe for everyone in the PC space" at videogame conference Casual Connect in Seattle. The Valve boss continued, saying that in the fallout from Windows 8, "we'll lose some of the top-tier PC/OEMs, who will exit the market. I think margins will be destroyed for a bunch of people." Newell criticised Windows 8 while talking about the future of the gaming industry, and you can read everything he said at VentureBeat.

As Microsoft announces a new tablet, technology experts offer their first impressions of the device, as well as insights into what the product could mean for Microsoft and its rivals. The BBC has compiled a round-up of what some of them are saying.

In its biggest-ever push into the hardware business, Microsoft unveiled a tablet computer called Surface that is designed to challenge Apple’s iPad. At an event here, the company showed off the device, which is about the same weight and thickness as an iPad, with a 10.6-inch screen. The tablet has a built-in “kickstand” that will allow users to prop it up for watching movies, and a detachable cover that will serve double duty as a keyboard.

Microsoft is expected to make a "major" announcement Monday. Speculation about the Los Angeles media event is that the company plans to unveil either a tablet computer or a system that uses an upcoming version of Windows to help people access TV shows and movies across a range of devices.

The device, running a new version of the Windows operating system, would be the first computer of the company’s own design — and would be aimed squarely at Apple’s iPad.

The world of Wintel - Microsoft, Intel and the Taiwan-based companies that build the computers their products power and run on - is taking a huge collective bet on Windows 8.

Microsoft has announced that it will be launching a new music service known as Xbox Music. Xbox Music will offer more than 30 million songs on Xbox 360s, Windows 8 PCs, tablets and phones.

Microsoft is launching the most complete preview yet of its forthcoming Windows 8 operating system, the biggest redesign since Windows 95.

Microsoft's usual plan is to offer a free upgrade to users of older versions of Windows to bump up to the next release version. This time around there will be a cost, according to sources.
