SUMMARY
Shell extensions for file names with no file extension can be registered under the following:

[HKEY_CLASSES_ROOT\.] For example, to associate a program (for example, Notepad.exe) to open all files with no extension, use the following registry keys:

[HKEY_CLASSES_ROOT\.] @=""

[HKEY_CLASSES_ROOT\.\shell]

[HKEY_CLASSES_ROOT\.\shell\open]

[HKEY_CLASSES_ROOT\.\shell\open\command] @=" %1" Here is an alternative method:

[HKEY_CLASSES_ROOT\.] @="NoExtFile"

[HKEY_CLASSES_ROOT\NoExtFile]

[HKEY_CLASSES_ROOT\NoExtFile\shell]

[HKEY_CLASSES_ROOT\NoExtFile\shell\open]

[HKEY_CLASSES_ROOT\NoExtFile\shell\open\command] @=" %1" NOTE: "NoExtFile" is not a predefined name, and therefore it can be anything. Adding other shell extensions is similar to adding shell extensions for file names with extensions.
