Works for me:
$ cd /proc/registry/HKEY_CLASSES_ROOT/\*
$ ls -F
AlwaysShowExt  InfoTip  shellex/
$ cat InfoTip
prop:Type;Author;Title;Subject;Comment;Size
$ cd shellex
$ /bin/pwd
/proc/registry/HKEY_CLASSES_ROOT/*/shellex

The problem in your demo is that not all registry entries are keys - some (including hkcr/*/InfoTip) are values.  In /proc/registry, registry keys map to directories, registry values map to files, and the contents of the values are found by reading the files.
