SAN FRANCISCO (AFP) - Microsoft releases Windows 7 to the world on Thursday as the US software giant tries to regain its stride after an embarrassing stumble with the previous generation operating system Vista. Its a big deal for Microsoft, analyst Rob Enderle of Enderle Group in Silicon Valley said of the Windows 7 launch. Windows Vista was a train wreck. While computer users may not give much thought to operating systems that serve as the brains of their machines, the programs are at the heart of Microsofts global software empire. Microsoft operating systems run more than 90 percent of the computers on Earth. Importantly for Microsoft, versions of its popular programs such as Office, Outlook and Excel evolve to work better with successive Windows releases. Winning users of new Windows systems translates into increased sales of other packaged software for the Redmond, Washington-based company. Vistas dismal reception in the market broke Microsofts rhythm regarding hooking people on upgraded software. Computer users held firm to Windows XP, shunning much-maligned Vista. Microsoft is still a packaged software company, Enderle said. If people dont buy their updated packages, they feel it. Microsoft apparently learned a lesson from Vista and worked closely with computer makers, users and software developers while crafting Windows 7. More than eight million people have dabbled with Windows 7 since Microsoft began a beta test phase in January, according to Parri Munsell, director of consumer product management for the Windows client group. Early reviews praise Windows 7 for being everything Vista should have been. We always listen to our customers, but we took an even more thoughtful and pragmatic process this time around, Munsell told AFP. We feel really good that people have been trying it for themselves. Windows 7 features winning raves include enabling computers, televisions, radios, digital picture frames and other smart devices in homes to talk to each other. Windows 7 also lets people use PCs to record television programs and then watch shows on demand at any Internet-linked computer using Microsofts Live service. Touch-screen capabilities built into Windows 7 should give birth to monitors that further blur lines between televisions and PCs, according to Munsell. Microsofts primary objective with Windows 7 was to simplify the lives of PC users, according to Munsell. This is going to be the next XP where it sticks around for a very long time, said analyst Matt Rosoff of Directions On Microsoft, a private firm focused on tracking the software firm. It performs well with a lot of hardware and software, and then it gets out of the way. It is not flashy, but it is solid. He added that Windows 7 works surprisingly well on netbooks low-cost bare-bones laptop computers that have devoured market share in the recent grim economic times. Windows 7 will be available pre-loaded on personal computers as of Thursday, and people who bought Vista machines in recent months will be able to upgrade free. Upgrading a home computer to Windows 7 will cost from 120 dollars to 220 dollars, depending on the version. As well-built as Windows 7 is, it probably wont boost consumer PC purchases, which depend heavily on the economy, according to Rosoff. A lot of corporations clinging to Windows XP are expected to upgrade to Windows 7, but after Microsofts new Office 2010 suite of business applications is released next year. This kind of gets Microsoft back on track with its core business, Rosoff said. It is not going to be something that takes the world by storm, but it is a solid operating system that people will be relying on for years. The failure of Vista to catch on hurt Microsoft competitively, giving Apple the opportunity to woo PC users to Macintosh computers. Apple could benefit anew if PC users faced with switching operating systems go for Macintosh machines instead of Windows 7, according to analysts. Microsoft has been faulted in the past for lacking the type of marketing pizzazz for which longtime rival Apple is famous. Microsoft has devoted an ample budget to advertising Windows 7. Microsoft has already been lambasted for hokey online videos describing how people can throw Windows 7 launch parties in their homes. Microsoft and television studio Fox announced that Windows 7 will be the theme of an animated Family Guy television show featuring musical numbers, comedy sketches, and celebrity guests. The fact that Microsoft is trying new things is actually pretty unique, Enderle said. They are going to try to show that Microsoft and innovative marketing is not an oxymoron.
