Although no one waits in long lines for a new edition of Windows anymore, the debut Thursday of Microsoft's latest software that runs PCs is part of why buying a computer is starting to feel fun for the first time in years.

Windows 7 is expected to work better than its predecessor, Vista. At the same time, Microsoft's marketing has gotten savvier and PC makers have followed Apple Inc.'s lead by improving hardware design. Computers with the Windows operating system suddenly seem a lot less utilitarian.

‘‘If you line up the six or seven most interesting PC designs, people will say, `Wow. I didn't know all of that could be done with a PC,’’’ Microsoft CEO Steve Ballmer said in an interview.

Windows 7 is designed to look cleaner than Vista, streamlining the ways people can get to work, with fewer clicks and fewer annoying notifications. Setting up home networking to share photos and music won't require an advanced degree in information technology. Plugging in a new device won't set off a mad hunt online for driver software, which tells the equipment how to work with an operating system.

Making a version of Windows that people like, rather than tolerate, is critical for Microsoft. Most people don't choose Windows as much as they end up with it, because it's familiar and affordable. But it's conceivable Microsoft will have to work harder to win people over, thanks to a small but growing threat from Apple's Macs and a forthcoming PC operating system from Web search nemesis Google Inc.

Vista fell flat because it didn't work with many existing programs and hardware. Microsoft fixed many of Vista's flaws but didn't spread the word, instead allowing Apple to attack with ads that pit a dorky office stiff (PC) against a casual creative type (Mac) and paint Vista PCs as unjustifiably complex.

It took a while, but Microsoft finally fired back. It hired Crispin Porter + Bogusky, a hip advertising firm, and set aside $300 million to portray Windows as warm and human. The ‘‘I'm a PC’’ campaign that emerged isn't universally well-liked, but the ads have arguably transformed the face of Windows from a pasty nerd to an adorable little girl named Kylie who e-mails pictures of her pet fish to her family without help from a grown-up.

Windows 7 also is arriving in the early days of a golden age for PC design.

For years, Apple has been making computers for people willing to pay a premium for design: sleek, metal-encased laptops with brilliant screens; swanlike iMacs that stash the workings of the computer behind an enormous flat monitor, perched atop a minimalist base; the MacBook Air notebook, thin enough to fit in a manila envelope. Meanwhile, the most notable shifts in PCs have been from beige plastic to black, or from chunky square notebooks to ones with slightly rounded edges.

Now, PC makers are starting to experiment with size, shape and colour at all price levels.

Windows 7 friendly to netbooks

Netbooks, the tiny, inexpensive, low-powered laptops that have been the PC industry's saving grace through the recession, are no longer just shrunken corporate PCs. To entice people to slip them into a purse and carry them everywhere, netbooks are made in a rainbow of colours and array of textures. Microsoft stumbled by making Vista too lumbering to run on netbooks, but even premium versions of Windows 7 will work on the little devices.

Even mid-range notebooks, costing $500 to $800, now have enormous screens and custom covers. At the higher end, PC makers have adopted Apple's thin-and-light concept and etched patterns into sleek metal cases.

Windows 7 feeds into this design craze in part by adding deeper support for touch-screen controls, leading such PC makers as Dell Inc. and Hewlett-Packard Co. to add ‘‘multi-touch’‘ screens that respond to finger gestures.

The plummeting cost of memory and computing power make this shift possible. Now any computer is good enough to surf the Web and do most daily tasks, because nearly all have fast processors and massive hard drives. So instead of racing to provide the most gigahertz or gigabytes, PC makers are zeroing in on aesthetics.

PC makers plan to unveil their latest in colourful and lightweight machines Thursday, an orchestration that was possible because Microsoft coordinated with PC makers earlier than usual. This is ‘‘a very different Microsoft,’’ said Alex Gruzen, an executive in Dell's consumer PC division. Gruzen said his team worked closely with Microsoft to fix things people didn't like about Vista - such as its slow boot-up time - rather than waiting, as in the past, for the software maker to ‘‘just throw the (operating system) over a fence’‘ for Dell to install on PCs.

Part of Apple's success stems from having control over both hardware and software. By better aligning those components, Microsoft and computer makers could get some of the same benefits, and cooler PCs could squash Apple's gains. Apple now has 11 per cent of the U.S. personal-computer market, up from 5 per cent when Vista debuted, according to analysts at IDC.

Xinhua adds: Hundreds of people attended events in New Zealand's Wellington and Auckland on Thursday morning to mark the world's first launch of Microsoft's Windows 7 operating system.

In Auckland's Queen Elizabeth Square, throngs of people tried to win Hewlett-Packard computers loaded with the new operating system, given away every 10 minutes throughout the event by All Black rugby team captain Richie McCaw. In Wellington's Civic Square, a similar exercise also took place.
