On Windows 7 I can search for updates, in the box on the start button > then find Windows Updates> then Change settings. It is here you can alter how the updates are managed.
I have browers Chrome for speed, but no good with Facebook nor Ancestry.
I have Firefox for Ancestry to download images.
I wouldn't touch any IE at all, but I still get updates for their latest brower, I am not that much of a tekky, but as far as I know even when using other browers IE is still involved, so it's a good idea to keep updating it.
I downloaded IE 8 some time ago and it really didn't get on well with my computer so I uninstalled it and everything went back to norma. I have now hidden this update and don't see it at all.
