Did u enable "Hidden files/folders" option in Search settings?
And to remove other context menu options, u can remove them by going to following keys:
Code:
HKEY_CLASSES_ROOT\*\shell
HKEY_CLASSES_ROOT\*\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Directory\shell
HKEY_CLASSES_ROOT\Directory\shellex\ContextMenuHandlers
HKEY_CLASSES_ROOT\Drive\shell
HKEY_CLASSES_ROOT\Drive\shellex\ContextMenuHandlers
Remember to take a backup first before playing those keys.
