Cumulative Update for Windows 10 (KB3147458) breaks Explorer, Start Menu, desktop, apps

After installing KB3147458 today, Explorer, the Start Menu, my desktop, and all my non-Win32 apps broke.

Here are the problems:

  • Clicking the start menu does nothing. Pushing the Windows key does nothing.
  • Clicking the search icon on the taskbar does nothing.
  • Clicking the show desktop button on the taskbar does nothing.
  • Trying to open Calculator gives an error: "Explorer.EXE Class not registered". The Calculator icon on my taskbar does not render.
  • Trying to open Control Panel via Run gives an error: "::{26EE0668-A00A-44D7-9371-BEB064C98683} No such interface supported"
  • Trying to open folders via Run gives an error: "[File path here] No such interface supported"
  • shellexperiencehost.exe does not run
  • Windows Photo Viewer does not open. Thumbnails for images on the desktop do not render.

Before the update, I was unable to open the MSN News and MSN Weather apps. I have a feeling that the security patches for IE and Edge have something to do with these new problems.
