Josh Rollyson <dinodrac () WEBTV NET> quotes someone saying:
Windows hides file types for some files even with HideFileTypes turned
off.

Do a search of your registry for the value "NeverShowExt", starting at:
HKEY_LOCAL_MACHINE\Software\CLASSES\
Which is mirrored at:
HKEY_CLASSES_ROOT\
I found that there were 10 occurrences on my (fairly UNLoaded
installation)
ALL of which I have now changed to "AlwaysShowExt"!
If you have much other M$ or Office software on your machine, you may
find more!
& it is quite easy for any program to conceal *any* file extension by
this means!

Argh.  How very Microsoftian.

Note that you need to use regedit.exe, not regedt32.exe, to search for the
'NeverShowExt's.  Also, you need to reboot for your changes to take effect.
