Deleting IE was one of the smartest moves I ever made computing wise.
I'm curious as to how you use Widows Update without IE? I know Fire fox has a plugin that will allow you to open a page in IE but how would you do that if you deleted IE?
I don't do windows update anymore. honestly, i perhaps shouldn't have deleted ie, as it did indeed break a few things... but given I don't use my computer for much it wasn't a big issue...
