沙滩星空的博客使用命令或脚本更改手动代理设置，是通过修改注册表项来完成的。
rem 禁用代理
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyEnable /t REG_DWORD /d 0 /f
rem 删除代理IP地址
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v ProxyServer /f
rem 禁用自动配制脚本（地址也被删除）
reg delete "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings" /v AutoConfigURL /f
rem 禁用自动检测设置
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v DefaultConnectionSettings /t REG_BINARY /d 4600000000 /f
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v SavedLegacySettings /t REG_BINARY /d 4600000000 /f自动设置代理

::开启：
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v DefaultConnectionSettings /t REG_BINARY /d 46000000020000000900 /f
""关闭：
reg add "HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Connections" /v DefaultConnectionSettings /t REG_BINARY /d 46000000030000000100 /f手动设置代理

echo 设置完毕在一个进程中， 设置和取消不能都执行，---- 要么设置，要么取消。 但如果第一次运行时，只进行设置代理，退出后再进运行，只进行取消，这是没有问题的。简单说说他给出的解决方案：每次设置或取消代理时，都新建一个进程，在新的进程中处理，处理完之后关掉进程。参考http://blog.csdn.net/debug__boy/article/details/8432879提供新的解决方案，国外大神的文章http://huddledmasses.org/setting-windows-internet-connection-proxy-from-c/：代码如下：
