How & where to know about new updates for MS Produ

[Stuntgp2000]

Hello everyone,

I frequently face this problem, I don't know neither how nor where to know about NEW Microsoft updates & products (because most of the time Microsoft release an update, then later on it add it the list of updates such as v4.windowsupdate.com/catalog if it's an update for windows)

My question is, is there a link in Microsoft web page that lists all updates and NEW ones that where released for Windows XP SP2, Office SP1 ? because this way I can check it frequently to see if there is a new update.

I hope I could explained !

Thanks in advance.
