@Heywood_J: I know. I want to embrace it except I am so embraced to get b slapped. And yeah it is extremely frustrating that I cannot simply uninstall and reinstall the browser back to normal. Just complete fail from security stand point. Sorry for the spam click, was trying to hit reply. @Sven Goot: I did the my first try. Same error pop up and MSN is slow as hell. @elmer: I couldn't do it on IE10, so, I still don't know how to do it yet. I seriously just want a browser has no Quirk mode. The reality is, even in compatibility scenario, IE9 mode is going to work better. I hate this stupid feature that causes more grief than solving problems. @Jim: yeah that's basically what happened, except I cannot restore from the damage without image store.
