I confirmed as per MSDN article "Registry Entries":

When you install the Visual FoxPro OLE DB Provider, the installation program updates your system's registry, HKEY CLASSES_ROOT, to add the following new keys:

HKEY_CLASSES_ROOT\VFPOLEDB

HKEY_CLASSES_ROOT\VFPOLEDB.1

HKEY_CLASSES_ROOT\Vfpoledb.ConnectionPage

HKEY_CLASSES_ROOT\Vfpoledb.ConnectionPage.1

HKEY_CLASSES_ROOT\VFPOLEDB.ErrorLookup

HKEY_CLASSES_ROOT\VFPOLEDB.ErrorLookup.1
