How to Make Internet Explorer 6 Crash Instantly
It's definitely no Konami code.
Most of you are likely to be running one of the most recent versions of your browser of choice, be it Internet Explorer, Firefox, Chrome, Opera or Safari; so hopefully this little bug won't take your browser down.
It's been discovered and now popularly reported that Internet Explorer 6 can be crashed by simply pointing the browser to:
ms-its:%F0:
Those without IE6 still lingering in their systems can get a demonstration of what happens in the video below.
KrebsonSecurity explains that this bug is the result of a pointer overflow in IE6 and the crash does not appear to work in newer versions of the browser.
Interestingly, it seems that this bug was found and reported to Microsoft back in 2004, but has yet to be patched. At the time, Microsoft engineers supposed believed there were no severe security consequences of this bug, leaving it a fix for a service pack – but that fix never arrived.
While the true damage of this flaw isn't severe, it could still cause many annoyances if malware (or a prankster) were to change the default start page to "ms-its:%F0:", rendering the browser unusable without a more advanced IE option tweak.

My company FINALLY "upgraded" to IE7 a couple of months ago, after IE8 came out. I don't get it. IE8 is faster, more stable and more secure than IE7. Why would we upgrade to that??? Another one of the joys of working for a large company.
Can one not just go to control panel then hit Network and Internet Settings then click Internet Options to get to the IE options without the browser and fix it without any of this regedit stuff?

Move along folks, nothing to see here.
(On another note, does anyone actually hit the "Send error report" button?
Make sure to put in redirects for IE6 only...
Let the death of IE 6 be a universal effort.
Are you trying to give us all RSI?
All joking aside I don't, on my current system I don't get very many crashes. And when I do it displays a log which I copy and paste then e-mail in.
QQ loser
Oh and did I mention its Old? I forget easily
Seriously people need to dumb the old IE6
You do know viruses and malware can search for browser versions to target, right?

If you run v8 benchmarks on any IE, they'll crash.
Brilliant Idea!!!
Actually it's even easier to get around than THAT. In the start menu type http://google.com and your browser will launch to the URL you've just entered instead of your home page. Problem avoided and you can change your homepage from inside IE6.
