My IE10 seems to have its "Metro mode" disabled. I can't seem to use it. The Internet Explorer tile in the Metro Start Menu just brings me to desktop and opens IE (in the desktop instead of opening it in Metro). I barely recall it was working (goes into Metro when opened in the start menu) when Win8DP was newly installed. I can't exactly figure out what cause it or how to bring back its "Metro mode".

The only tweak I used on it was:

I tried to undo that, but it's still the same (IE Metro Tile opens it in "desktop mode")

If it helps, I also applied a few others (which I don't think affects IE, but still...):
One of the themes from the program "Blue Poison" (just a theme and nothing else) and

Though, normally, I use Firefox instead of IE and I just found this out when I accidentally clicked IE's Metro tile. But it's still bothering me.

Try Refresh using this tutorial and see whether it fix the problem.
Refresh Windows 8

Tried it and it worked. It felt a little too extreme though.

just set ie10 as the default browser. it worked for me.

and where do you do that its not like ie9 it ask you to ck where is 10 tks

Thanks to this thread I got my metro style IE :-)
