Как получить версию Windows?

procedure TForm1.WinVer;
var WinV: Word;
begin
WinV := GetVersion AND $0000FFFF;
Edit6.Text := IntToStr(Lo(WinV))+'.'+IntToStr(Hi(WinV));
end;
Функция выдает следующее - 4.10
Как можно таким же простым способом получить полную версию - 4.10.222

Вот еще один пример. Мне он нравиться больше всего. Я его обычно использую в своих программах. Он гибкий и предоставляет максимум информации.

Этот пример должен работать на всех версиях Windows
