Computer not responding when creating a folder

As ikellenberger mentioned DropBox was involved in my case, however I never installed it. The insight came from this thread. Apparently there was a Windows App named App Installer that suspiciously had a DropBox icon. After uninstalling that, the problem stopped immediately with no reboot required.

App Installer

To uninstall:

  1. Press the Windows key
  2. Type Apps & features into the search bar and click the result
  3. In the search box that says Search this list type App Installer
  4. If the search returns a result that has a DropBox icon, click on it and click the Uninstall button
