Summary: Default right-click action changes to Cmd for folders in Windows 10. Double-clicking folders shows the association error message.
I've seen a few cases where the default action for folders somehow changed from Open to Cmd, showing up in bold when you right-click a file system folder. And clicking it shows the following file association error message:
This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel.
