On a Windows 98 2nd Edition O/S, quite a few of the files no longer have associations. And they are not all the same type of files, there's many different ones. When I try to open, I get the "open with" window, and it wants me to pick something. Unfortunately I don't know what to pick to try and reset them.
I've run virus scan, and there is no virus.
