I understand that from the article, but I was questioning the KB931125 optional roots certificate update which was offered to two of my computers and not the Win 7 laptop.
(Ifirst saw this in screenshots in the Security Forum regarding the current Windows Updates where it is listed as optional.)
It seems a bit confusing what is going on. My home computer (7 Home Premium) did get the root update. My work computer (7 Pro) didn't. Both are 32-bit.
I agree about the confusion. After rebooting the laptop after the attempted installs, my boot time went from 52 seconds to 81 seconds. I didn't care for that, so last night I used the system restore - now the computer is taking 92 seconds to boot. I give up.
My Windows 7 computers are both 64 bit and Vista is 32 bit.
