I'm not sure I understand what you mean... I installed 2008 R2 with the base version of WSUS and tested that everything installed fine on 2000/XP/vista and this is the case. Thereupon, i'm go to bed. its late here.

WSUS works on vista SP2 yes. Just like 2000 SP4 or XP SP3.

Of course. I installed SHA2 support on 2008 R2 and all updates have been downloaded.

Hi all, Personally I use WSUS, it's more convenient than offline scan or zip packs. There is almost all updates unlike offline scan which doesn't contain IE8 for example. And for those who are missing there is only to import them. It's work very well
