In a recent survey of its customers running Microsoft’s Windows operating systems, Devil Mountain Software found that roughly one-third of enterprises that purchased a New PC with Windows Vista pre-installed downgraded to Windows XP. Major businesses have not deployed Microsoft’s latest OS due to compatibility issues and its reputation as a resource hog, according to Craig Barth, chief technology officer at Devil Mountain. “What we’re seeing is a trend that organizations are either bypassing Vista, delaying adoption, or debating whether to stick with Windows XP,” he said.
