注册表限制使用U盘的几种方法

1.写保护操作：

1、运行REGEDIT,
2、展开HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet,
3、右击Control项,选择新建,重命名新建项为WriteProtect,并设置其值为00000001(十六进制),然后刷新即可.
4、若要取消对闪存写保护的限制,将值改为00000000即可.

2. 禁用U盘：

1、运行REGEDIT,
2、展开HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR,
3、右击Start，将其值改为4，则可将U盘禁用，若要取消禁用，只需将4改回3.

3.注册表法
禁止使用USB存储设备的注册表内容如下：
在记事本把代码保存成一个名为lockusb.reg的reg文件，然后双击该文件导入注册表就完成了禁止该计算机使用USB存储设备的操作。所有用户都无法用USB存储设备了。

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]

开启USB存储设备使用权限的注册表内容如下：
代码保存成一个以unlockusb.reg后缀的reg文件，双击该文件导入注册表就完成了开启该计算机使用USB存储设备的操作。所有用户都可以使用USB存储设备。

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR]
"Type"=dword:00000001
"Start"=dword:00000003
"ErrorControl"=dword:00000001

4.U盘的表现：在硬盘里可以找到，能看到容量，也可以打开，可就是不能往里面写东西，格式化时，又提示说什么请先去掉写保护。。。真是狂晕啊，。。。

修复过程：
三、修改注册表
1、打开注册表win+r(即开始－运行)键入regedit.exe
2、进入如下目录HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\StorageDevicePolicies；
HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolicies
若没有StorageDevicePolicies项则建立此项
（附：这是2000的系统，XP的我没进去仔细看过，如果懒得动的话，复制下面这些另存文本，再改为*.reg双击导入注册表即可）
Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet002\Control\StorageDevicePolicies]
"WriteProtect"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies]
"WriteProtect"=dword:00000000

[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\StorageDevicePolicies]
"WriteProtect"=dword:00000000
3、建立Dword值命名为WriteProtect并令其值为0
4、重启时带U盘重启，当系统重启至U盘灯闪时，拔掉U盘
5、系统重启完毕后插入U盘，U盘操作恢复正常
