Определить тип учётной записи

Сабж. Как это реализовать в делфи? Нужно оприделить админская учётка или огранич.

Вот так:

function IsAdmin: Boolean;
const
   SECURITY_NT_AUTHORITY: TSIDIdentifierAuthority =
     (Value: (0, 0, 0, 0, 0, 5));
   SECURITY_BUILTIN_DOMAIN_RID = $00000020;
   DOMAIN_ALIAS_RID_ADMINS = $00000220;
var
  hAccessToken: THandle;
  ptgGroups: PTokenGroups;
  dwInfoBufferSize: DWORD;
  psidAdministrators: PSID;
  x: Integer;
  bSuccess: BOOL;
begin
  Result   := False;
  bSuccess := OpenThreadToken(GetCurrentThread, TOKEN_QUERY, True,
    hAccessToken);
  if not bSuccess then
  begin
    if GetLastError = ERROR_NO_TOKEN then
      bSuccess := OpenProcessToken(GetCurrentProcess, TOKEN_QUERY,
        hAccessToken);
  end;
  if bSuccess then
  begin
    GetMem(ptgGroups, 1024);
    bSuccess := GetTokenInformation(hAccessToken, TokenGroups,
      ptgGroups, 1024, dwInfoBufferSize);
    CloseHandle(hAccessToken);
    if bSuccess then
    begin
      AllocateAndInitializeSid(SECURITY_NT_AUTHORITY, 2,
        SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS,
        0, 0, 0, 0, 0, 0, psidAdministrators);
      {$R-}
      for x := 0 to ptgGroups.GroupCount - 1 do
        if EqualSid(psidAdministrators, ptgGroups.Groups[x].Sid) then
        begin
          Result := True;
          Break;
        end;
      {$R+}
      FreeSid(psidAdministrators);
    end;
    FreeMem(ptgGroups);
  end;
end;

попробуй это

function IsAdmin: Boolean;
const
   SECURITY_NT_AUTHORITY: TSIDIdentifierAuthority =
     (Value: (0, 0, 0, 0, 0, 5));
   SECURITY_BUILTIN_DOMAIN_RID = $00000020;
   DOMAIN_ALIAS_RID_ADMINS = $00000220;
var
  hAccessToken: THandle;
  ptgGroups: PTokenGroups;
  dwInfoBufferSize: DWORD;
  psidAdministrators: PSID;
  x: Integer;
  bSuccess: BOOL;
begin
  Result   := False;
  bSuccess := OpenThreadToken(GetCurrentThread, TOKEN_QUERY, True,
    hAccessToken);
  if not bSuccess then
  begin
    if GetLastError = ERROR_NO_TOKEN then
      bSuccess := OpenProcessToken(GetCurrentProcess, TOKEN_QUERY,
        hAccessToken);
  end;
  if bSuccess then
  begin
    GetMem(ptgGroups, 1024);
    bSuccess := GetTokenInformation(hAccessToken, TokenGroups,
      ptgGroups, 1024, dwInfoBufferSize);
    CloseHandle(hAccessToken);
    if bSuccess then
    begin
      AllocateAndInitializeSid(SECURITY_NT_AUTHORITY, 2,
        SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS,
        0, 0, 0, 0, 0, 0, psidAdministrators);
      {$R-}
      for x := 0 to ptgGroups.GroupCount - 1 do
        if EqualSid(psidAdministrators, ptgGroups.Groups[x].Sid) then
        begin
          Result := True;
          Break;
        end;
      {$R+}
      FreeSid(psidAdministrators);
    end;
    FreeMem(ptgGroups);
  end;
end;
