Sometimes, with installing and uninstalling various applications, you may end up with incorrect or invalid file associations in Windows XP. Here's how to repair them.
HOW TO: Change File Associations in Windows XP
Fix file associations from the Command Line: Did you leave the Always Use This Program To Open This File option turned on? Do you want to change it back so it prompts you to specify a program each time? To delete the association with that file type, at the command prompt enter the command ASSOC.EXT= [where .EXT specifies the extension of the file type whose association you want to delete (e.g., .WAV for wave files)]. Now whenever you double-click on the file of that type, the system will ask you what program you want to use to open the file.
