UnauthorizedAccessException while creating a registry key

I am learning how to add a shortcut to Windows context menu to my application. I came across this article and I tried this. This is the code it uses to create a key in the registry.

private void btnAddMenu_Click(object sender, System.EventArgs e)
{
    RegistryKey regmenu = null;
    RegistryKey regcmd = null;
    try
    {
        regmenu = Registry.ClassesRoot.CreateSubKey(MenuName);
        if(regmenu != null)
            regmenu.SetValue("",this.txtName.Text);
        regcmd = Registry.ClassesRoot.CreateSubKey(Command);
        if(regcmd != null)
                regcmd.SetValue("",this.txtPath.Text);
    }
    catch(Exception ex)
    {
        MessageBox.Show(this,ex.ToString());
    }
    finally       
    {
        if(regmenu != null)
            regmenu.Close();
        if(regcmd != null)
            regcmd.Close();
    }        
}

      

        
        
        
      

    

The problem is that I run it through my admin account, it works fine. But when I do it through another account that doesn't have admin rights, it throws this exception.

system.unauthorizedaccessexception access to the registry key is denied

      

        
        
        
      

    

Now, if I were to use this code in one of my own applications to create a shortcut in the context menu, I cannot be sure that every user will run it as Administrator, right?

Is there a way in C # to elevate user privileges when creating a registry key?

If you know of any other way to add an item to the Windows context menu, I'll be interested in them too.

Thank.
