IE11 BrowserWindow different than IE10 BrowserWindow

  I'm testing an application on multiple IE versions (IE8, IE9, IE10, and IE11). I have a TestComplete license on my IE8 machine and my IE10 machine and so far this has been working well for all of my needs. Most objects in IE9 are either like IE8 or IE10, but I ran into a snag. The BrowserWindow object has changed between IE10 and IE11. 

  I have mapped the BrowserWindow in IE10 using the following attributes.

ObjectType = BrowserWindow

WndCaption = *Windows Internet Explorer

  This works for IE8, IE9 and IE10, but TC can't find the IE11 object using these attributes. I'd upgrade my IE10 box to IE11, but the last time we did that the box never worked like a true version of IE10 again and it had to be rebuilt to get it back to a clean IE10 version. Does anyone know what the WndCaption value for IE11 is? Or does anyone know another attribute that I could use to replace the WndCaption that would work for all 4 versions of the IE browser? 

Thanks in advance,
