Allow me to play Devil's Avocate for a moment ...
I, for one, use Windowblinds because I appreciate how they look and all the hard work the skinners go to, making them works of art in many cases. Security issues aside, every "improvement" to IE in my opinion has merely reduced the taskbar, etc to Chrome clones ... If I wanted Chrome I'd use it ... I like how much more was skinned in earlier versions of IE.
If there is a way to return all the skinned areas to IE 9 etc .......... PLEASE, someone tell me how and I'll update the browser!
(Thank you all for allowing my rant.)
