The clock is ticking on the demise of some downgrade rights for Windows 7, an analyst said Thursday.
Last year, Microsoft said that customers could downgrade new machines purchased with Windows 7 Professional to the older Windows XP Professional for a limited period. The deal ends 18 months after the introduction of Windows 7 -- in other words, in late April 2011 -- or when Microsoft launches Windows 7 Service Pack 1 (SP1), whichever comes first.
Nearly two months ago, Microsoft acknowledged it's working on Windows 7 SP1. It has not yet set a release timetable, however.
