我想检测当前的Windows操作系统是32位还是64位。如何使用C ++实现呢？我不想要处理器类型我想要操作系统的位类型。这是因为您可以在64位处理器上安装32位操作系统。

推荐答案

要调用的函数是 IsWow64Process 。它告诉你的32位应用程序是否在64位Windows上运行。

The function to call is IsWow64Process. It tells your 32-bit application if it is running on a 64 bit Windows.

如果程序编译为64位，它就会知道。

If the program is compiled for 64 bits, it will already know.
