Originali Title: delete file association
I have a file type (.HDP) which has accidentally become associated with Windows 'Movie Maker', which was offered as the first option to open the file.
I would like to reset it so that it has no default program associated with it.
I am running Windows 8 Pro with Media Center
Intel i7 CPU 930 @ 2.8GHz
64 bit operating system
How can I remove this association?
