درود
با سورس زیر میتونید چک کنید ایا یوزر کاربری ادمین هست یا نه ؟تابع زیر نیاز به فراخوانی یونیت windows رو دارد.

کد:

function IsAdmin: Boolean;
const
  // SID related constants
  SECURITY_NT_AUTHORITY: TSIDIdentifierAuthority =
    (Value: (0, 0, 0, 0, 0, 5));
  SECURITY_BUILTIN_DOMAIN_RID = $00000020;
  DOMAIN_ALIAS_RID_ADMINS = $00000220;
var
  AccessToken: Windows.THandle;       // process access token
  TokenGroups: Windows.PTokenGroups;  // token groups
  InfoBufferSize: Windows.DWORD;      // token info buffer size
  AdmininstratorsSID: Windows.PSID;   // administrators SID
  I: Integer;                         // loops thru token groups
  Success: Windows.BOOL;              // API function success results
begin
  Result   := False;
  Success := Windows.OpenThreadToken(
    Windows.GetCurrentThread, Windows.TOKEN_QUERY, True, AccessToken
  );
  if not Success then
  begin
    if Windows.GetLastError = Windows.ERROR_NO_TOKEN then
      Success := Windows.OpenProcessToken(
        Windows.GetCurrentProcess, Windows.TOKEN_QUERY, AccessToken
      );
  end;
  if Success then
  begin
    GetMem(TokenGroups, 1024);
    Success := Windows.GetTokenInformation(
      AccessToken, Windows.TokenGroups, TokenGroups, 1024, InfoBufferSize
    );
    Windows.CloseHandle(AccessToken);
    if Success then
    begin
      Windows.AllocateAndInitializeSid(
        SECURITY_NT_AUTHORITY, 2,
        SECURITY_BUILTIN_DOMAIN_RID, DOMAIN_ALIAS_RID_ADMINS,
        0, 0, 0, 0, 0, 0,
        AdmininstratorsSID
      );
      {$R-}
      for I := 0 to TokenGroups.GroupCount - 1 do
        if Windows.EqualSid(AdmininstratorsSID, TokenGroups.Groups[I].Sid) then
        begin
          Result := True;
          Break;
        end;
      {$R+}
      Windows.FreeSid(AdmininstratorsSID);
    end;
    FreeMem(TokenGroups);
  end;
end;
