Microsoft already extended the XP deadline once, but it shows no signs it will do so again. The company has declined to meet with Gruman to consider the petition. Microsoft is aware of the petition, it said in a statement to The Associated Press, and "will continue to be guided by feedback we hear from partners and customers about what makes sense based on their needs."
Gruman said he'd keep pressing for a meeting.
"They really believe if they just close their eyes, people will have no choice," he said.
In fact, most people who get a new computer will end up with Vista. In 2008, 94 percent of new Windows machines for consumers worldwide will run Vista, forecasts industry research group IDC. For businesses, about 75 percent of new PCs will have Vista. (That figure takes into account companies that choose to downgrade to XP.)
Although Microsoft may not budge on selling new copies of XP, it may have to extend support for it.
Al Gillen, an IDC analyst, estimated that at the end of 2008 nearly 60 percent of consumer PCs and almost 70 percent of business PCs worldwide will still run XP. Microsoft plans to end full support -- including warranty claims and free help with problems -- in April 2009. The company will continue providing a more limited level of service until April 2014.
Gillen said efforts like Gruman's grass-roots petition may not influence the software maker, but business customers' demands should carry more clout.
"You really can't make 69 percent of your installed base unhappy with you," he said.
Some companies -- such as Wells Manufacturing Co. in Woodstock, Ill. -- are crossing their fingers that he's right. The company, which melts scrap steel and casts iron bars, has 200 PCs that run Windows 2000 or XP. (Windows 2000 is no longer sold on PCs. Mainstream support has ended, but limited support is available through the middle of 2010.)
Wells usually replaces 50 of its PCs every 18 months. In the most recent round of purchases, Chief Information Officer Lou Peterhans said, the company stuck with XP because several of its applications don't run well on Vista.
"There is no strong reason to go to Vista, other than eventually losing support for XP," he said. Peterhans added that the company isn't planning to bring in Vista computers for 18 months to two years. If Microsoft keeps to its current timetable, its next operating system, code-named Windows 7, will be on the market by then.
