I have seen your post on other forums.
Most important: There have been many reports of the "August Update" giving problems. The extreme is that the computer will no longer boot into the OS.
This is the MS context :
"Microsoft is recommending that EVERYBODY do this regardless of whether you have a current problem or not. There is a strong possibility that ANYBODY could experience the problem and be unable to boot windows at any time with these updates installed, or have display issues. With the increased use on websites of dynamic fonts that are loaded as and when needed to display on a website, that do not use the default installed fonts, the problems can affect anybody and cause an IE crash on almost any site
Open the Programs and Features item in Control Panel, and then click View installed updates. Find and then uninstall any of the following update that are currently installed:
◦ KB2982791
◦ KB2970228
◦ KB2975719
◦ KB2975331"
Link: Link Removed
Pure luck that
1. I do not have Automatic updates selected, and,
2. I was in no hurry to download the updates, by the time I looked at them, the download had been closed., so they are not installed.
