Microsoft wasn't quite ready to comment when rumors about yet another reprieve for Windows XP first starting circulating late last week, but that now seems to have changed, with a spokesperson for the company reportedly confirming in an email to InformationWeek that it is indeed pushing the cut-off date back six months, all the way to July 31st, 2009. According to the spokesperson, that's being done to ensure that customers moving to Vista are "making that transition with confidence and that it is as smooth as possible," adding that, "providing downgrade media for a few more months is part of that commitment." Or, you know, it could have something to do with the fact that some folks don't want to move to Vista at all. Take your pick.
