Please use a subject which concisely describes your problem, so that people can tell easily if they can help. "Help me ,Please [ C# application]" does not tell anyone anything useful - since you have "C#" as your tags...

I need to disable USB port of the computer using c# ..

below is the solution which is working for 32 bit windows but not working 64 bit ... I need a same function which can do the same thing for 64 bit ....

//disable USB storage...
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 4, Microsoft.Win32.RegistryValueKind.DWord);

//enable USB storage...
Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 3, Microsoft.Win32.RegistryValueKind.DWord);

i can read the value on windows 64 bit but can not write the value....
RegistryKey registryKey = RegistryKey.OpenBaseKey(Microsoft.Win32.RegistryHive.LocalMachine, RegistryView.Registry64);

Console.WriteLine("registryKey" + registryKey);

registryKey = registryKey.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR");
Object val = registryKey.GetValue("Start");
Console.WriteLine("The val is:" + val);
here i am getting the current val which is set ...
but when i try to open in write mode...
registryKey = registryKey.OpenSubKey(@"SYSTEM\CurrentControlSet\Services\USBSTOR", true);
and try to set a value 4 to disable it cant work...
registryKey.SetValue("Start", 4);
