In Start Search type Regedit and hit the Enter key.
Navigate to the following registry key:
HKEY_CLASSES_ROOT\Directory\shellex\PropertySheetHandlers\Sharing
If the Sharing key is not present then you need to create this key. Right-click on PropertySheetHandlers and then select New > Key.
Name this key as Sharing and hit Enter.
Now a default REG_SZ key will be automatically created. Double click on it and change its value to {f81e9010-6ea4-11ce-a7ff-00aa003ca9f6} and then click OK.
Reboot.
