I have a desktop and laptop that I updated from Windows 7 to Windows 8 and now to Windows 8.1. A few days ago Internet Explorer 11 disappeared from the modern UI on both machines (I do synchronize settings with SkyDrive). It woks fine in the desktop interface. I frankly don't use in in the Modern UI, but I don't like the fact that it just disappeared. IE does not show up when I use the Store to look at All Apps on my computers, and it does not show up using the Win 8.1 "Start Button". I also can't find it the Store to download. Ideas? Thanks.
