Today, we will discuss about Enable and Disable USB Port using C#.Net.Now let's go to our Coding section.

First Create an Application in the VS 2008 C#.

Create Two Button in the Form.

One is called "Enable".

Another one is called "Disable".
Go to Your Form Coding Section:

Declare namespace :

using System.Security.Principal; 

Declare Variable for Checking login user is Admin or Normal User

public static bool IsUserAnAdministrator;
private void btn_Enable_Click(object sender, EventArgs e)
            Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 3, Microsoft.Win32.RegistryValueKind.DWord);

        private void btn_Disable_Click(object sender, EventArgs e)
            Microsoft.Win32.Registry.SetValue(@"HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR", "Start", 4, Microsoft.Win32.RegistryValueKind.DWord);

        private void FrmEnabledisableUSBPort_Load(object sender, EventArgs e)
            if (IsAnAdministrator())
                btn_Disable.Enabled = true;
                btn_Enable.Enabled = true;
                btn_Disable.Enabled = false;
                btn_Enable.Enabled = false;
To check User is Admin or Not.
        bool IsAnAdministrator()
            WindowsIdentity MyIdentity =  WindowsIdentity.GetCurrent();
            WindowsPrincipal MyPrincipal =  new WindowsPrincipal(MyIdentity);
            return MyPrincipal.IsInRole(WindowsBuiltInRole.Administrator);
