Mine were all XP-related updates. Rebooted after installing and did not have any issues.
But I use only FireFox and had to log in to everything last fall. Tried everything to avoid re-entering passwords, even here on FR. Finally I started a new profile that didn't have that problem when I came across the very simple solution.
Firefox: Tools>>Options>>Privacy>>History
Check: "Accept cookies from sites"
On the line with "Keep until:," Select in menu: "they expire"
I had selected the menu "I close FireFox" which deleted them. No further problems after that.
Thanks. A real response. I don’t use FireFox, but I am becoming interested in it after reading so many threads on how it does not fall victim to these kinds of things.
I haven’t had the same problem since I rebooted, either, but I’m using Windows. Beginning to wish I had FireFox.
