神秘Windows 7引发新猜想 Vista还要加油 (2007-08-22 12:21:00)
摘要：就在Vista大卖之时，Windows 7作为它的下一个版本开始吸引了更多眼球。虽然微软对细节依旧透露甚少，但在美国奥兰多刚刚结束的微软内部会议上，它的庐山真面目开始逐渐显露。去年11月，Gartner Group的一份报告提到，Windows Vista将是微软最后一个桌面操作系统。回想起Windows 3.0在1990年正式发布以来在世界范围内卷起的一系列Windows风暴，Windows 95发布前一天晚上人们排队购买的盛况，以及微软一系列组合拳Windows 3.0、Windows 3.2、Windows 95、Windows 98、Windows 2000、Windows XP直至Windows Vista，对于Vista将会是Windows终结者的论断，人们不禁要问，难道我们未来的桌面操作系统不会再有全新面貌了？今年1月，在美国消费电子大会CES 2007上，盖茨终于站出来为微软的王牌正名，Windows 7将是Vista的下一个版本代号，Windows将继续昂首向前。为什么新操作系统的名字是Windows 7呢？最简单的答案就是因为Windows Vista版本号是Windows 6.0，所以Vista的版本号就顺理成章是7.0。它目前还仅仅是微软的内部代号，等问世的时候也许会有一个更为瞩目的名字。但是Windows 7到底会是什么样子？现在，关于Windows 7的新消息又来了。就在7月19日在美国奥兰多举行的一个微软内部区域销售会议上，微软再次讨论了Windows 7的计划。Windows 7更贴近用户比尔·盖茨曾经介绍道，下一代Windows将在64位计算、语音、数字墨水方面进行加强， Windows 7上市将会在2到4年之间。盖茨表示：下一代Windows将更加以用户为中心,提供以用户为中心的服务。现在，如果用户从一台机器移动到另外一台机器，用户可能需要重新安装自己需要的应用程序，并且升级。在不同电脑之间转移信息不是一件容易的事情，甚至是一件非常痛苦的事情。微软正在做的努力是，通过Live服务研究用户的兴趣。这些研究成果在将来的某个时候可能提供给用户最大的便利。例如，即便用户在使用公共场合的电脑，微软也能通过网络提供最常用的各种用户设置，包括主页、个人文件、字体设置、收藏夹等等，任何用户需要的东西都可以通过网络提供。在Vista系统中，数字墨水......
