Hi,

I think you cannot block USB of client machine using ASP.NET application. but you can take a chance of doing using ActiveX, but still am not sure that you will find an option.

Hi Bhargavpp,

You can do this by modifying the registry via C# code.

C#

using Microsoft.Win32;
RegistryKey key;
key = Registry.LocalMachine.OpenSubKey
         ("SYSTEM\\CurrentControlSet\\Services\\UsbStor");
key.SetValue("Start", 4, RegistryValueKind.DWord);  //disables usb drives
key.SetValue("Start", 3, RegistryValueKind.DWord);  //enables usb again

Any devices already connected will remain there, but no new usb drives plugged in will be automatically mounted.

Happy Coding..!

Thank you,
Vamsi
