启用禁用USB接口

一个小工具，功能有启用禁用外网、USB接口，可由服务端socket长链接进行操控客户端从而达到实现前边的这些功能，这里贴上核心代码，先给上启用禁用USB接口吧，这个方法可随时启用禁用，之前用过一个改usb接口状态那个方法不大行，对于已经插进去的没啥作用了，这个是后来改过的

启用USB

public bool EnableUSB()
{
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindows", "RemovableStorageDevices", "");
}
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices", "{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}", "");
}
SetRegistValue("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}", "Deny_Read", "0", "REG_DWORD");
SetRegistValue("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}", "Deny_Write", "0", "REG_DWORD");
bool blDevices = SetRegistValue("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}", "Deny_All", "0", "REG_DWORD");
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SYSTEMCurrentControlSetservicesUSBSTOR"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SYSTEMCurrentControlSetservices", "USBSTOR", "");
}
bool blUsbStor = SetRegistValue("HKEY_LOCAL_MACHINE", @"SYSTEMCurrentControlSetservicesUSBSTOR", "Start", "3", "REG_DWORD");
if (GetSystemIs64() == "64")
{
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREWow6432NodePoliciesMicrosoftWindowsRemovableStorageDevices"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREWow6432NodePoliciesMicrosoftWindows", "RemovableStorageDevices", "");
}
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREWow6432NodePoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREWow6432NodePoliciesMicrosoftWindowsRemovableStorageDevices", "{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}", "");

}
return blDevices && blUsbStor;
}

 禁用USB

public bool DisableUSB()
{
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices"))
{
CreateRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindows", "RemovableStorageDevices", "");
}
if (!IsExistRegistKey("HKEY_LOCAL_MACHINE", @"SOFTWAREPoliciesMicrosoftWindowsRemovableStorageDevices{53f5630d-b6bf-11d0-94f2-00a0c91efb8b}"))

return systemtype;
}
catch (Exception ex)

}
catch (Exception ex)

}
private RegistryValueKind GetValueKind(string typeInfo)
{
switch (typeInfo)
{

以上内容都是比较固定死的，没什么技术含量，这些内容可以直接拿着作为helper用了

（下一个是启用禁用外网）
