软件介绍：

Easun Studio Windows 系统切换工具是是安装多Windows系统的用户的福音。不知道您是否有这种体会，为了工作需要，安装了多个Windows（比如中文Win98、英文Win98及Win2000）,可是切换起来却太是困难，Windows 2000 还提供了启动菜单，而多Win95/98/Me根本上就没有这种菜单供您选择，就只有自己在DOS下用批处理进行切换。网上进行多系统切换的工具也可谓多也，但是几乎都是用自己的模块替换BOOT区来完成的，而且都是在DOS（字符界面）下进行切换选择，既麻烦有不安全，而且界面操作复杂，那能不能有一种界面友好，安全，方便在Windows界面下进行操作的系统切换工具呢？路杨就是本着这个原因开发这个软件的，该软件界面大方美观，操作上手，不用自身模块覆盖BOOT区，安全可靠，工作在Windows95/98/Me/2000/Xp 环境下，让您彻底抛开DOS界面和字符界面！另外，本软件还有设置系统和恢复IE设定的功能，当然，这就是附加功能了。
