review windows update

how do i find what patches was installed on PC/server and when(date).
Microsoft Baseline Security Advisor and was able to find out what wwas
installed, but not when it was installed. Also I gave a try to Shavlik NetChk
Pro -- same result.
But when you go to windows update website and click on 'review windows
update' you see what and when it was installed -- amore complete history. Now
i can dow it on 1-10 servers, but i have 80 of them, is there a script or
software that can do it for me? I dod delete windws update installation files
form %windir% folder
Any hel
Thank You
