I've always had updates set to inform only, but was surprised to see on shutdown (early hours of Oct 13th) that there were updates being installed!
Sure enough, when I checked next morning, the setting was on automatic! I've re-set it to inform only.
Since then, I've had problems with Outlook (2010) and IE 8:
With Outlook, especially first thing when a number of new emails have arrived, I sometimes get 'not responding' happen a few times. It clears after 1-2 minutes.
With IE, some sites are taking a long time to open/load, as are links to other pages/objects within sites. WindowsSecrets is one of those sites which is working very slowly for me. (It took a while to open the site, then a good few minutes to load the 'post a reply' page. This happens on a number of sites, but not every time. Other sites work normally.
I also found only yesterday after seeing the disk usage going down gradually, that system restore has re-set itself back to my old setting of 18%. I changed it to 12% a month ago and regained 4GB of space. I've now re-set it again.
Basically, has anyone else had these problems which seem to have manifested since the October updates last week?
