Some time ago, I was edited the Windows XP registry so that, in Windows Explorer, files with unknown extensions would be opened with a text processor capable of displaying files in hex. This proved to be a bad idea for large files, because of time wasted before opening by the application could be gracefully aborted. I know the registry change involved either or both of HKEY_CLASSES_ROOT\.* and HKEY_USERS\S-1-5-..._Classes\*, but I don't know what to change them back to.

I'm fairly ignorant of the structure of the registry and would be grateful to anyone who can point me to any helpful information.
