Repairing the context menu of folders

Repairing the context menu of folders:

Navigate to "HKEY_CLASSES_ROOT\Directory\shell" key. Select the incorrect command and
delete it. Now on the right hand side of the Registry editor double click on the value
named Default. Replace the name of the undesired context menu command with open. This way
you transfer further controls to file type folder. Now open windows explorer. Click on
tools->folder options. Select the entry none folder in the "File types" tab. Click
advanced. Only one action other than "Open" can be defined in the dialog box, which should
be set as default. Confirm the dialog box with "OK" and close.
Now when you open windows explorer, dbl clicking on any folder will open it rather than
exploring.
