Yes.

You have done no initialisation whatsoever in that code, just used
random values and handed them to a function. I'm surprised it isn't
crashing.

Something more like

  char utilisateur[200] = { 0 };
  DWORD taille = sizeof(utilisateur)/sizeof(utilisateur[0]);
  if (GetUserName(&utilisateur[0], &taille) != 0)
  {
     ...
  }

(though I'd personally use vectors, using a two stage process to firstly
get the size, secondly get the content into a resized vector).
