Last update, a few weeks ago, both of my laptops lost my subscribed to
newsgroups in Mesnews. I had to resubcribe to them all on both laptops.
There were other oddities too, before and after the update.

I have brought this laptop out of hibernation to find the screen
display was entirely monotone (white and sepia), on checking a little
closer, it had another big update to install. As soon as I clicked
reboot and update, the screen colours returned to normal. Is this MS's
new way to indicate an update install is needed?
