[HKEY_CURRENT_USER\Software\Microsoft\Windows\ CurrentVersion\Policies\Explorer]
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\ CurrentVersion\Policies\Explorer]
Tweak: Open your registry and find the key [HKEY_CLASSES_ROOT\Directory\shell] then rename it from 'shell' to 'shell.old'.
Do the same with the key [HKEY_CLASSES_ROOT\Folder\shell] and rename it to [...\shell.old].
Once complete the two original keys should now be called [HKEY_CLASSES_ROOT\Directory\shell.old] and [HKEY_CLASSES_ROOT\Folder\shell.old] respectively.
