USB端口注册表禁用教程（开启、关闭与启用方法）

想要禁用USB可以使用组策略编辑器中的安全设置，如果你需要使用注册表来禁用USB端口，那么下面分享给大家比较简单的教程，包含了禁用USB端口和启用USB端口。方便大家在电脑上限制USB的使用，有需要的朋友可以一试。

注册表禁用USB端口：

操作方法如下：把下述代码复制粘贴到一个文本文件中，接着将该文件保存为名为XXX.reg的注册表文件，最后双击这个文件进行导入即可。

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR] "Type"=dword:00000001 "Start"=dword:00000004 "ErrorControl"=dword:00000001 "ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,\ 52,00,49,00,56,00,45,00,52,00,53,00,5c,00,55,00,53,00,42,00,53,00,54,00,4f,\ 00,52,00,2e,00,53,00,59,00,53,00,00,00 "DisplayName"="USB 大容量存储设备" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Security] "Security"=hex:01,00,14,80,90,00,00,00,9c,00,00,00,14,00,00,00,30,00,00,00,02,\ 00,1c,00,01,00,00,00,02,80,14,00,ff,01,0f,00,01,01,00,00,00,00,00,01,00,00,\ 00,00,02,00,60,00,04,00,00,00,00,00,14,00,fd,01,02,00,01,01,00,00,00,00,00,\ 05,12,00,00,00,00,00,18,00,ff,01,0f,00,01,02,00,00,00,00,00,05,20,00,00,00,\ 20,02,00,00,00,00,14,00,8d,01,02,00,01,01,00,00,00,00,00,05,0b,00,00,00,00,\ 00,18,00,fd,01,02,00,01,02,00,00,00,00,00,05,20,00,00,00,23,02,00,00,01,01,\ 00,00,00,00,00,05,12,00,00,00,01,01,00,00,00,00,00,05,12,00,00,00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Enum] "Count"=dword:00000000 "NextInstance"=dword:00000000

注册表启用USB端口：

操作方法：把下述代码拷贝至一个文本文件当中，接着将其保存为XXX.reg即可！

Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR] "Type"=dword:00000001 "Start"=dword:00000003 "ErrorControl"=dword:00000001 "ImagePath"=hex(2):73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,\ 52,00,49,00,56,00,45,00,52,00,53,00,5c,00,55,00,53,00,42,00,53,00,54,00,4f,\ 00,52,00,2e,00,53,00,59,00,53,00,00,00 "DisplayName"="USB 大容量存储设备" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Security] "Security"=hex:01,00,14,80,90,00,00,00,9c,00,00,00,14,00,00,00,30,00,00,00,02,\ 00,1c,00,01,00,00,00,02,80,14,00,ff,01,0f,00,01,01,00,00,00,00,00,01,00,00,\ 00,00,02,00,60,00,04,00,00,00,00,00,14,00,fd,01,02,00,01,01,00,00,00,00,00,\ 05,12,00,00,00,00,00,18,00,ff,01,0f,00,01,02,00,00,00,00,00,05,20,00,00,00,\ 20,02,00,00,00,00,14,00,8d,01,02,00,01,01,00,00,00,00,00,05,0b,00,00,00,00,\ 00,18,00,fd,01,02,00,01,02,00,00,00,00,00,05,20,00,00,00,23,02,00,00,01,01,\ 00,00,00,00,00,05,12,00,00,00,01,01,00,00,00,00,00,05,12,00,00,00 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR\Enum] "Count"=dword:00000000 "NextInstance"=dword:00000000

大家有没有留意到，实际上这两段代码近乎相同，仅“Start”= 后面的内容存在些许差异。开启状态对应的是“Start”=dword:00000003，而禁用状态对应的则是“Start”=dword:00000004 。此外，也能够按照以下教程进行手动操作。

1. 同时按下Win键与R键，在弹出的运行框中输入“regedit”，以此启动注册表编辑器。

2、依次展开如下分支：

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\USBSTOR] （注意你原内容中CurrentCntrolSet拼写有误，这里修正为CurrentControlSet ）

3、在右侧的窗格中找到名为“Start”的DWORD值，双击，在弹出的编辑对话框中将其数值数据修改为十六位进制数值“4”。 4、点“确定”按钮并关闭注册表编辑器，重新启动计算机，使设置生效。重启后，当有人将USB存储设备连接到计算机时，虽然USB设备上的指示灯在正常闪烁，但在资源管理器当中就是无法找到其盘符，因此也就无法使用USB设备了，等同于被认为禁用USB。 以上方法大家可以自由选择都是比较简单的哦。
