Do you use OneNote and send things from IE to OneNote? Have you updated to Win8.1 and IE11? Have you noticed that your IE11 and OneNote 2013 are no longer compatible and in fact you get a nasty message about restarting OneNote and configuring it when you try to send things to OneNote?
OneNote needs to set itself up before you can send to it. Please run OneNote and then try sending again.
Of course, starting, stopping, reinstalling, playing with, or doing anything else with OneNote does not resolve this. However, the fine folks at http://www.onenotegem.com/ have provided a simple explanation and solution.
