Anyone have this? How is it?

I was thinking of downloading and installing it but when I was searching this topic on the internet I read a comment of someone who could not watch videos on Youtube anymore and that he had a hard time getting rid of it after. Youtube is close to 100% of my time online (when im not watching im listening while being on the internet or doing something else) so I can't accept that. Did that happen to anyone here after having Internet Explorer 10 with your Windows 7?
