To all who have answered this post/question
It seems pretty obvious that Microsoft Update works VERY slowly with Vista. I made several comparisons with XP and Win7, using the same broadband connection and the differences are OBVIOUS (no need of any precise measurement... a sundial will do it).
So, it is of me clear that either
- the system in VISTA is so inefficient that it takes a lot of time to figure out which updates are needed
OR
- the server used for VISTA downloads is a slow and inefficient machine...
I'd like to hear from Microsoft...
