I too found that going back to an older version fixed it.
Here is what else I found...
I shut down the PC and it again had updates ready to install. I let them install and restarted the PC and now IE was broken again! I did a search for IE no Internet access after latest security update and found that in some cases when IE installs the latest
security update it selects a proxy server that effectively blocks program access to the Internet through IE. Since I don't use IE I never experienced any of the noted issues with my PC after the latest update. I however have a program that uses IE and thats
when I found that I had the issue.
What I did was follow these steps. Within IE I selected tools>Internet options>advanced tab> "reset" and now it all works fine.
