有时我们会遇到IE中自动检测设置无法取消的情况，具体表现为“自动检测设置”默认是打勾的却显示为灰色无法操作，这时我们可以通过修改注册表来取消IE中的“自动检测设置”，具体方法如下： 新建一个记事本文档写入以下内容 Windows Registry Editor Version 5.00 [HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionInternet SettingsConnections] "DefaultConnectionSettings"=hex:3c,00,00,00,05,00,00,00,01,00,00,00,00,00,00, 00,00,00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,90,b1,e4,38,dc,92,c6,01, 01,00,00,00,c0,a8,71,fa,00,00,00,00,00,00,00,00 "SavedLegacySettings"=hex:3c,00,00,00,85,00,00,00,01,00,00,00,00,00,00,00,00, 00,00,00,00,00,00,00,01,00,00,00,00,00,00,00,90,b1,e4,38,dc,92,c6,01,01,00, 00,00,c0,a8,71,fa,00,00,00,00,00,00,00,00 保存为REG后缀文件，双击运行即可。
