It basically allows you to execute an application with elevated privileges. If you want to achieve a similar effect under Windows, open an administrative prompt and execute your command from there. Under Vista, this is easily done by opening the shortcut while holding Ctrl+Shift at the same time.
它基本上允许您以提升的权限执行应用程序。如果您想在 Windows 下实现类似的效果，请打开管理提示并从那里执行您的命令。在 Vista 下，这很容易通过打开快捷方式同时按住 Ctrl+Shift 来完成。
That being said, it might very well be possible that your account already has sufficient privileges, depending on how your OS is setup, and the Windows version used.
话虽如此，您的帐户很可能已经拥有足够的权限，具体取决于您的操作系统的设置方式以及所使用的 Windows 版本。
