Earlier today an update to Visual Studios began rolling out, KB3001652 (Update for Microsoft Visual Studio 2010 Tools for Office Runtime). The update was intended to install the 2010 tools for Office Runtime while updating the premature shut down thread in the WPF user interface, fix the lag occurring on touch enabled when shutting down Visual Studios that use the WPF, and address the incorrectly displaying installation Trust Prompt "Unknown Publisher"_even when the publisher is fully trusted.
