Unfortunately, the patch doesn't fix the actual flaw. It's a duct tape solution for the CURRENT exploit and I've already seen a working demo of how to re-exploit the same damn flaw. So yes, get the patch and if you are still using IE, feel somewhat safe for another couple days/weeks.

You know what the patch does? It changes a registry setting. That's IT! How many billions of dollars is microsoft making again? IE not updated from 6.0 in 4 years? World's economy mostly dependant on MS software?
Anyone see a problem here?
