var
updateSession : olevariant;
updateSearcher : olevariant;
searchResult : olevariant;
update : olevariant;
i : integer;
begin

//Set updateSession = CreateObject("Microsoft.Update.Session")
updateSession := CreateOleObject('Microsoft.Update.Session');

//Set updateSearcher = updateSession.CreateupdateSearcher()
updateSearcher := updateSession.CreateupdateSearcher;

//Set searchResult = _
//updateSearcher.Search("IsInstalled=0 and Type= 'Software '")
searchResult := updateSearcher.Search('IsInstalled=0 and Type= ''Software ''');

//For I = 0 To searchResult.Updates.Count-1
// Set update = searchResult.Updates.Item(I)
// WScript.Echo I + 1 & " > " & update.Title
//Next
for i := 0 to searchResult.Updates.Count-1 do
begin
update := searchResult.Updates.Item[I]; //或许是Item(i)
//memo.lines.add(update.Title);
end;

//后面的和前面的差不多一样,改改就行了
end;
