Computerworld reports that Gartner analysts today urged organizations to start planning for the end of Windows 7

Microsoft has pledged to support Windows 7 until Jan. 14, 2020, or five years and five months from today. The company's "Mainstream" support -- the front end of a 10-year stretch -- ends Jan. 13, 2015, but the firm will continue to provide security patches for the popular OS for another five years after that in its "Extended" support phase.

With more than five years left on the support clock -- and with many enterprises having just wrapped up their migration to Windows 7 -- why start planning now?
