最近有变态需求要求把企业无盘的用户帐号和Windows帐号一体化，就研究了下Windows帐号的创建，有几个坑，第一是Windows内置帐号是不能改名的，Windows自己能改名其实其内部机制也是先创建新的再删除老的，并且要关联注册表和用户文件， 第二是当创建新的管理员帐号时要先创建成普通用户，再加入到Administrators组里。话不多说，上示例代码（为了省事，代码是chatGPT生成的，只简单调试就OK了).
#include <windows.h>
#include <lm.h>
#include <lmaccess.h>
#pragma comment(lib, "NETapi32.lib")

NET_API_STATUS status = NetUserDel(nullptr, username);
if (status == NERR_Success) {
// Account removed successfully
return TRUE;
}
else {
// Error occurred while removing account
return FALSE;
}
}
bool DoesUserExist(const wchar_t* username)
{
USER_INFO_0* user_info = NULL;
bool exists = false;
NET_API_STATUS result = NetUserGetInfo(NULL, username, 0, (LPBYTE*)&user_info);
if (result == NERR_Success)
{

NetApiBufferFree(user_info);
}
return exists;
}
