代码注入在 Vista 或 Win7 上不起作用？

Question

所以我不得不让两个朋友在他们的 Vista 和 Windows 上测试可执行文件。 Win7操作系统。注入的代码都没有执行（即使以管理员身份运行），但控制台打开/关闭。通过 WriteProcessMemory 和 CreateRemoteThread 进行代码注入在 Vista 或 Win7 上仍然有效吗？

代码

在 Visual Studio 2008 上使用 /RTCu 进行编译，以防止在 Windows XP 上远程线程终止后进程崩溃。

Answer 1

并不意外。 Vista 和 Windows 7 增强了安全性。许多恶意软件使用代码注入作为绕过 Windows XP 安全机制的步骤之一，我很高兴看到 Microsoft 修复了此问题。
