操作系统有所耳闻，它是微软已推出的三种操作系统内核之一，是一种实时操作系统。虽然它是一种实时操作系统，但是从96年发布v1.0到现在，它的主要用途都在民用领域，比如Pocket PC、SmartPhone、Automation。不像VxWorks，应用于航空航天、军事等领域。现在linux、VxWorks厂商也都看好嵌入式民用市场，激烈竞争在所难免。我看好Windows CE，因为微软在PC领域实在太强，用户也早已熟悉了微软的产品，把PC下的技术移植到嵌入式领域，首先在操作界面方面就占了上风。 -operating systems have heard, it is Microsoft has launched three of the operating system kernel, is a real-time operating system. Although it is a real-time operating system, but from the 96 released v1.0 now, which are mainly used in civilian areas, such as Pocket PC, SmartPhone, Automation. Like VxWorks, used in aerospace, military and other fields. Now Linux, VxWorks manufacturers are optimistic about embedded civilian market, fierce competition is inevitable. I like Windows CE, Microsoft in the PC field is too strong, users are already familiar with Microsoft products, the PC technology into the embedded field in the first operation on the interface prevailed.
