判断当前程序是否以管理员身份运行，，代码如下：


#include <iostream> #include <windows.h> using namespace std; // 判断当前程序是否以管理员身份运行。 bool IsProcessRunAsAdmin() { SID_IDENTIFIER_AUTHORITY NtAuthority = SECURITY_NT_AUTHORITY; PSID AdministratorsGroup; BOOL ret= AllocateAndInitializeSid( &NtAuthority, 2, SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS, 0, 0, 0, 0, 0, 0, &AdministratorsGroup); if (ret) { CheckTokenMembership(NULL, AdministratorsGroup, &ret); FreeSid(AdministratorsGroup); } return ret== TRUE ; } int main() { cout << "Hello world!" << endl; if(IsProcessRunAsAdmin()) { cout<<"Run as administrator ........"<<endl; } else { cout<<"Run as Not Administrator ......"<<endl; } getchar(); return 0; }

程序结果：
普通方式运行（直接双击运行）:
