翻译:Windows Modes
Windows can run in two modes:386 enhanced mode and standard mode.When you type win by itself,Windows starts in the most appropriate mode for your system.(You can find out which mode Windows is running in by choosing the About command from the Help menu in Program Manager.)Windows uses the following criteria when determining which mode to use:Windows starts in 386 enhanced mode if you have an 80386SX computer (or higher) with at least 640K of conventional memory plus 1024K of extended memory.However,more memory is required to use the more advanced features of Windows.Windows starts in standard mode if you have an 80286 computer (or higher) with at least 640K of conventional memory and 384K of extended memory.Windows also starts in standard mode on 80386 computers that have less than 2MB of free memory.
Windows运行模式：
Windows有两种运行模式：386增强模式和标准模式，如果在命令行中仅键入WIN，Windows将根据系统配置情况启动适当的运行模式。(用户可在程管理器的帮助菜单中选择About观察Windows的运行模式)。
Windows用以下的判定准则确定其运行模式：
如果是80386SX或更高档的机器，至少有640KB的常规存贮器，加上1024KB的扩充存贮器，Windows用386增强模式运行。当然，存贮器越多，就越能发挥Windows的功能。
如果是80286或更高档的机器，至少有640KB的常规存贮器，加上384KB的扩充存贮器，Windows用标准模式运行。同样，如果80386的计算机中的可用存贮器少于2MB，Windows也只能启动标准模式运行。
