USB存储设备管理.本人为防止在电脑上使用U盘移动U盘等设备,以防止感染病毒,自己给USB存储设备增加了一开关,代码比较简单,很实用.本程序不会影响到其它USB设备的正常使用.

unit USBManager;

interface

uses
  Windows, Messages, SysUtils, Classes, Graphics, Controls, Forms, Dialogs,registry,
  StdCtrls;

type
  TForm1 = class(TForm)
    Button1: TButton;

    procedure FormCreate(Sender: TObject);
    procedure Button1Click(Sender: TObject);
  private
    Fusb: Boolean;
    { Private declarations }
  public
    { Public declarations }
  end;

  Fusb := False ;
  if  not Freg.OpenKey('SYSTEM\CurrentControlSet\Services\USBSTOR',true) then

  end;
  if Freg.ReadInteger('start')= 3 then
  begin
    Fusb :=True;
    Button1.Caption := '禁用USB存储设备';
