用dump出的trm32.ime替换原来的文件。再次运行输入法管理器。选天然码，点“属性”，将弹出MESSAGEBOX说没有指纹盘或disk serial不对。control-n激活trw2k，“pmodule”，“确定”后，回到trw2k：

:00401514 89442410 mov dword ptr [esp+10], eax
:00401518 8B442434 mov eax, dword ptr [esp+34]
:0040151C 50 push eax

:0040154B E9A1000000 jmp 004015F1

注意这时是在getdiskserial.exe的领空。（也就是说trm32.ime产生getdiskserial.exe进程）。往上看，注意0040151D处的call 004011B0，在此处下断点，再次运行进入“call 004011B0”来到这：

017F:00401439 50 PUSH EAX
017F:0040143A 8D8C2488030000 LEA ECX,[ESP+0388]
017F:00401441 6A04 PUSH BYTE +04
017F:00401443 51 PUSH ECX
017F:00401444 6A00 PUSH BYTE +00
017F:00401446 6A00 PUSH BYTE +00
017F:00401448 6A01 PUSH BYTE +01
017F:0040144A 56 PUSH ESI
017F:0040144B FF1514604000 CALL `KERNEL32!DeviceIoControl` 〈=调用vxd
017F:00401451 56 PUSH ESI
017F:00401452 FF151C604000 CALL `KERNEL32!FindCloseChangeNotification`
017F:00401458 8BB42490130000 MOV ESI,[ESP+1390]
017F:0040145F 8A843484030000 MOV AL,[ESP+ESI+0384]
017F:00401466 84C0 TEST AL,AL 〈==是否有指纹盘或disk serial ？
017F:00401468 744D JZ 004014B7 〈==没有就跳
017F:0040146A 8BC6 MOV EAX,ESI

017F:0040144B处调用diskserial.vxd绝对读磁盘，017F:00401468处是判断。因为没有指纹盘，将此处改为nop;nop;替换getdiskserial.exe（在window的system下）。

再次运行，这次可以来到“属性”窗口，点“确定”可来到注册窗口，我的机器码为123456789012，输入用户名leo_cyl,注册码12121212。下断点hmemcpy,跟踪来到这里：
