I came to the same issue as him that my Skype isn't working (plus all my Metro apps too). This is very clear to me that IE is somehow broken in some way because the so-called "apps" are just webpages. When I search for Internet Explorer, it says no result.
Scriptsis disabled. This is so weird.
alert popup showing up.
I believe that IE10 files might be corrupted, but IE10 is preinstalled when I bought the computer and it was working perfectly months before (to download Chrome :P).
Any idea on how to fix this and why did that happened?
