How can I change dat file extension back to unknown file?

Hi,
I don't know how to restore file type association in Windows to the default state with no associated program.
In Control Panel -> All Control Panel Items -> Default Programs -> Set Associations: When Windows not know which app should open a dat file type, it assigns a blank default icon to this file.
In my case, I associated dat file with wrong program by mistake and forgot to uncheck the box Always use the selected program to open this kind of file in open unknown file dialog. How do I delete/restore it?
