### 当前程序给自己获取管理员权限 ###

#include <stdio.h>
    #include <conio.h>
    #include <windows.h>
    
    VOID ManagerRun(LPCSTR exe,LPCSTR param)
    {
         //注意：会跳出提示。
        SHELLEXECUTEINFO ShExecInfo;
        ShExecInfo.cbSize = sizeof(SHELLEXECUTEINFO);
        ShExecInfo.fMask = SEE_MASK_NOCLOSEPROCESS ;
        ShExecInfo.hwnd = NULL;
        ShExecInfo.lpVerb = "runas";
        ShExecInfo.lpFile = exe;
        ShExecInfo.lpParameters = param;
        ShExecInfo.lpDirectory = NULL;
        ShExecInfo.nShow = SW_SHOW;
        ShExecInfo.hInstApp = NULL;
        BOOL ret = ShellExecuteEx(&ShExecInfo);
        //杀掉当前线程
        CloseHandle(ShExecInfo.hProcess);
        return;
    }
    
    int main(int argc,char *argv[]) {
        
        if(argc == 1) //初次运行，即双击EXE
        {
        
            ShowWindow(GetConsoleWindow(),SW_HIDE);
            printf("%s",argv[0]);
            ManagerRun(argv[0],"2");
            return 1;
        }else if(argc == 2) //再次运行,即上面那个ManagerRun
        {
        
            /*你的程序主代码在此*/
            printf("%s","hello world\n");
           
            getch();
        }
    
        return 0;
    }

### 打开指定的exe以管理员权限运行 ###

#include <stdio.h>
    #include <windows.h>
    
    int main(void)
    {
        
        SHELLEXECUTEINFO sei = {
         sizeof(SHELLEXECUTEINFO) };
        sei.lpVerb = TEXT("runas");
        sei.lpFile = TEXT("cmd.exe");//add  application  which you want to run as administrator here
        sei.nShow = SW_SHOWNORMAL;//without this,the windows will be hiden
        if (!ShellExecuteEx(&sei))
        {
        
            DWORD dwStatus = GetLastError();
            if (dwStatus == ERROR_CANCELLED)
            {
        
                printf("提升权限被用户拒绝\n");
            }
            else if (dwStatus == ERROR_FILE_NOT_FOUND)
            {
        
                printf("所要执行的文件没有找到\n");
            }
        }
    
        getchar();
        return 0;
    }

`cmd.exe` 可以换成自己需要调用的exe程序(写全路径) , 否则就需要配置环境变量,不然找不到

**注意: 不要自己掉自己否则死循环,窗口一直闪**
