'More information' coming up as 'This page doesn't exist'?

I'm checking some hidden optional updates and I want to get some information about them, but each one comes as 'This page doesn't exist'.

Is anyone else having a problem or is it just me, and if it is, why?

Thanks

I always have that problem, I just search for it without clicking on that link.

I've had it when there has been a new Windows update and the information is not available until a day or two later, but not with updates that have been available for a weeks.
