This problem occurs when you alter the "File Folders" entries via File Types dialog, to add a "Command Prompt here" or "Print Directory" feature for folders.

As you've learnt, "regsvr32 /i shell32" command fixes this problem.

I don't know how or when it changed, but the default action in the context
menu--the action taken when double-clicking on a folder in explorer--is
emboldened on Search rather than Open. So I have to right click every
folder and select open to navigate, otherwise it opens a search dialogue
instead. I figured out how to select a context menu default action years
ago, but can't remember how. Someone solve my problem.
