昨天突然想到我已有一个U盘，为什么不做一个Windows登陆时的usb Check呢？

1。在SDK Sample中有一个GinaStub的例子
    在WlxDisplaySASNotice 添加如下内容:

VOID
WINAPI
WlxDisplaySASNotice (PVOID pWlxContext)
{
    //======================= C O D E S N I P =========================
    // Add These Below

    int count = 0;
    while(!CheckUsbKey())
    {
        MessageBox(NULL, "Please Insert USB KEY", "Tips", MB_OK);
        if(count == 10) break;
        count++;
    }
    //====================================================================

    pfWlxDisplaySASNotice(pWlxContext);
}

//=============================
//   CheckUsbKey is here!!!
//=============================
BOOL CheckUsbKey()
{
    char filename[MAX_PATH+1];
    char drivename[3] = "A:";
    DWORD fix = 0x0001;
    FILE *file;
    char list[30];
    int numread;
    int i;

    DWORD drivermap = GetLogicalDrives();

    for( i = 2; i<26; i++)
    {
        if(drivermap & fix<<i)
        {
            drivename[0] = 'A' + i;

            if(DRIVE_REMOVABLE == GetDriveType(drivename))
            {
                _snprintf(filename, MAX_PATH+1, "%s//license.dat", drivename);

                file = fopen(filename, "r");

                numread = fread( list, sizeof( char ), 8, file );
                list[8] = '/0';

                if(numread == 8 && strcmp(list,"12345678") == 0) // your key
                {
                    fclose(file);
                    return TRUE;
                }

                fclose(file);

            }
        }
    }

    return FALSE;

}

2。新建一个内容如下注册表文件

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows NT/CurrentVersion/Winlogon]

"GinaDLL"="GinaStub.dll"

3。在U盘的根目录中新建一个license.dat，内容为12345678

4。将GinaStub.dll拷贝到System32目录下，导入注册表文件，重启即可。
