技术为破解元气桌面
技术点为API，PostMessage断点。
断点有两个，一个为PostmessageA，另一个为PostMessageW
断点功能为弹出窗口，我是从PostMessageW为入口点破解成功的。
PostMessageW的汇编代码如下
76AAF680 | 8BFF | mov edi,edi |
76AAF682 | 55 | push ebp |
76AAF683 | 8BEC | mov ebp,esp |
76AAF685 | 53 | push ebx |
76AAF686 | 8B5D 08 | mov ebx,dword ptr ss:[ebp+8] |
76AAF689 | 57 | push edi | edi:L"不支持此接口\r\n"
76AAF68A | 8B7D 0C | mov edi,dword ptr ss:[ebp+C] |
76AAF68D | 8BC7 | mov eax,edi | edi:L"不支持此接口\r\n"
76AAF68F | 2D 45010000 | sub eax,145 |
76AAF694 | 74 4C | je user32.76AAF6E2 |
76AAF696 | 83E8 48 | sub eax,48 |
76AAF699 | 74 47 | je user32.76AAF6E2 |
76AAF69B | 2D A6000000 | sub eax,A6 |

76AAF6AA | 50 | push eax |
76AAF6AB | 53 | push ebx |
76AAF6AC | FF15 64DBB476 | call dword ptr ds:[<NtUserQueryWi |
76AAF6B2 | 3B46 20 | cmp eax,dword ptr ds:[esi+20] |
76AAF6B5 | 5E | pop esi |
76AAF6B6 | 74 20 | je user32.76AAF6D8 |
76AAF6B8 | 8B45 10 | mov eax,dword ptr ss:[ebp+10] |
76AAF6BB | 50 | push eax |
76AAF6BC | 50 | push eax |
76AAF6BD | FF15 F8D2B476 | call dword ptr ds:[<GlobalSize>] |
76AAF6C3 | 50 | push eax |
76AAF6C4 | 6A 49 | push 49 |
76AAF6C6 | 53 | push ebx |
76AAF6C7 | E8 24480000 | call <user32.SendMessageW> |
76AAF6CC | 8BC8 | mov ecx,eax |
76AAF6CE | 85C9 | test ecx,ecx |
76AAF6D0 | 75 23 | jne user32.76AAF6F5 |
76AAF6D2 | 5F | pop edi | edi:L"不支持此接口\r\n"
76AAF6D3 | 5B | pop ebx |
76AAF6D4 | 5D | pop ebp |
76AAF6D5 | C2 1000 | ret 10 |
下断点F9运行跟踪，
跟踪堆栈返回到汇编代码。

由于call在复用代码，我只能修改关键跳转，
此处为所有PostMessageW的关键点，
修改后即可破解成功。
