This is the right approach, especially regarding Windows 8, which is in beta testing and will most likely ship toward the end of the year, said Michael Silver, a Gartner analyst.
Companies need to upgrade from Windows XP, which Microsoft will stop supporting in April 2014, and delaying such a move to wait for Windows 8 would be a mistake, Silver said.
"It's really important that organizations continue to get XP out," he said. "For most people, Windows 8 will be too late and Windows 7 is the one to focus on right now."
Gartner estimates that in developed countries, Windows 7, which began shipping in October 2009, has been fully implemented in about 10 percent of enterprises, while 55 percent are in the process of deploying it and 25 percent are just starting.
