Enterprise users say they are unfazed that support for Microsoft\u2019s Windows 98, Windows 98 Second Edition (SE) and Windows Millennium Edition (ME) ends in July.Microsoft will officially stop public and technical support\u2014including security updates\u2014for the legacy operating systems on July 11, according to information on its website. However, online self-help support will be available for the operating systems on Microsoft\u2019s support website until at least July 11, 2007.Microsoft originally planned to end support for Windows 98 and ME in January 2004, but extended that to June 30, 2006, before announcing in January that final support would come on July 11 to allow for some last security patches.Support may be ending for these once-popular operating systems this year, but an investigation by Computerworld indicates many enterprises have already upgraded to Windows 2000 and XP.IP Australia\u2019s service centre manager, Maria O\u2019Ryan, said Microsoft\u2019s decision to end support in July "doesn\u2019t concern me," because there is only one computer running Windows 98 remaining in the organization."It\u2019s being used as a test box to compare things until we upgrade as the client doesn\u2019t run on XP," O\u2019Ryan said. "We probably won\u2019t run the Windows 98 box past the deadline as the upgrade is due [for completion] in two weeks."At its peak, IP Australia had about 1,000 Windows 98 desktops\u00a0that were quickly upgraded to Windows XP over the space of "a few weekends.""We never really contacted Microsoft, or used the support anyway," O\u2019Ryan said, adding that she doesn\u2019t think many Windows 98 installations are left within the wider enterprise.O\u2019Ryan said IP Australia is "having a look" at Windows Vista, but could not reveal any upgrade plans.Echoing O\u2019Ryan\u2019s stance, an IT project manager at a utility company, who requested anonymity, said while there are only two Windows 98 machines left running logging software, the decision to end support is "not a big deal for us." Windows 98 and ME are less likely to be found in businesses than they are on home machines. According to a December 2005 Jupiter Research survey of nearly 2,300 PC customers, 16 percent were running Windows 98 or 98 SE in their homes, and 6 percent were running Windows ME.Microsoft recently pushed back the consumer release of the next major update to Windows Vista until January 2007. Jupiter media analyst Joe Wilcox said that means customers still running Windows 98 or ME\u00a0who must upgrade by July will most likely move to Windows XP, and forgo upgrading to Vista upon its release in January. This poses a concern for Microsoft, which "still is not getting people to upgrade as quickly as they would like," he said.-Rodney Gedda, Computerworld Today (Australia) (with Elizabeth Montalbano of the IDG News Service)This article is posted on our Microsoft Informer page.\u00a0For more news on the Redmond, Wash.-based powerhouse, keep checking in.For related news coverage, read Microsoft to Cut Support for Windows 98 & ME in July.Check out our CIO News Alerts and Tech Informer pages for more updated news coverage.
