Using XP-Pro OS I mistakenly Linked my Outlook.pst file extension to open with Outlook. How do I fix it?

I'm I headed to regedit?

Thanks.

You'd need to remove it from Default programs but its shouldn't cause problems (even if you had it linked to something stupid, like Excel) because that only affects the ability to double click to open files and the pst needs to be opened using File, Open, Outlook Data file.
