On my machine, .mat is associated to Matlab via the registry but I can not even run file to program association utility as it uses explorer to search for all file extension on the machine so it crashes too. I did not have much luck with the blogs so I wandered if anyone of you has  a suggestion how to solve this issue.

george,
Not help, but maybe info.
I have pretty plain Win7, x64, with office products loaded.
No such issues.
When new, it had .mat associated with office something.
All .mat files showed as shortcuts & would not show extensions, regardless of settings for show extensions & hide nothing.
Folder options, or equivalent, (non-registry editing) switched it to Matlab & have noticed no ill-effects.
Anyway, I guess that means that you are looking for something different: something in your setup.
