判断程序是否在虚拟机中运行(VC++)

VC++的代码，虽然有点老但是很实用，发出来留做备用！

#include "windows.h"
DWORD __forceinline IsInsideVPC_exceptionFilter(LPEXCEPTION_POINTERS ep);
bool IsInsideVPC();
bool IsInsideVMWare();
int CheckVPC();

#ifndef _DEBUG
#pragma comment(linker, "/ENTRY:EntryPoint")
#pragma comment(linker, "/SECTION:VPC,")
#pragma comment(linker, "/MERGE:.data=VPC")

int EntryPoint()
{
CheckVPC();
ExitProcess(0);
}
#else
int WINAPI WinMain(IN HINSTANCE hInstance, IN HINSTANCE hPrevInstance, IN LPSTR lpCmdLine, IN int nShowCmd )
{
return CheckVPC();
}
#endif // _DEBUG
int CheckVPC()
{
if(IsInsideVPC())
MessageBox(NULL, "你在虚拟电脑Microsoft Virtual PC中!", "提示", MB_OK|MB_ICONINFORMATION);
else if(IsInsideVMWare())
MessageBox(NULL, "你在虚拟电脑VMWare中!", "提示", MB_OK|MB_ICONINFORMATION);
MessageBox(NULL, "你在真实的电脑中!", "提示", MB_OK|MB_ICONINFORMATION);
return 0;
}

{

return EXCEPTION_CONTINUE_EXECUTION;
}
