High Resource Use by Start Screen

While diagnosing what I thought was a Windows Update failure, I discovered unrelated massive resource consumption and file scanning activity apparently tied to the Start screen in Windows 2012.

Symptoms:

10 to 20% constant CPU usage by Windows Explorer.

Rapid file scanning or Shared Folder usage in the case of folder redirection.

Triggers:

Resource consumption begins immediately after opening the Start screen and performing a keyboard search.

Closing the Start screen does not help.

Workarounds:

Sign out the current user.  This action will shut down Windows Explorer, preventing the unwanted symptoms until triggered again by a user.
