Microsoft extends Windows 7 shelf life as Windows 8 struggles
It seems that Windows 7 will remain on sale to business users until at least early 2015, if not longer, following a change to Microsoft’s Windows lifecycle.
As spotted by ZDNet, the updated lifecycle indicates that Microsoft has not yet decided on an end-date for the OS and could be a long way off yet.
Microsoft has promised to give businesses at least a year’s warning before it kills off Windows 7 Professional.
Doing a 180
In 2013, the company announced that it was forbidding new PCs to be preinstalled with Windows 7 Home Basic, Home Premium and Ultimate after October 31 2014. This would mean that any new hardware customers would be pushed onto Windows 8.
Microsoft hinted that end-of-sale date was the same for Windows 7 Professional. Later it backtracked when business customers threw up their hands in horror.
