winodws updates arc

Hi all,
My Exchange 2003 server was running but suddenly it’s crashed.
Luckily I had windows and system state backup and data storage
backup.

I have done following steps.
1. Restored windows 2003 (sp2) server image which I took on July
2008.
2. Restored System state backup (Which was latest)
3. Restored Exchange databases.


All went ok and now working fine.


Now I realised that windows updates are not up to date. When I try
from website its showing you have all latest updates. But I know that
this windows not been updated after July.


I guess this happening because I restore system state backup which
got
latest registry as well.


Can anyone tell how can I get latest windows updates?


Many Thanks
Asim
