RE:      Vanguard Windsor Funds


Dear Mr. Sandoe,

     The following follows today's discussion about your comments regarding
Post-Effective Amendment No. 109 that was filed yesterday.


Comment:          Prospectus - Plain Talk about the Portfolio Managers
                  (Windsor and Windsor II)
- --------------------------------------------------------------------------------
Comment:          Please verify that aside from the PMs listed in the
                  prospectus, no one else is jointly or primarily responsible
                  for the day to day management of fund assets.

Response:         Aside from the PMs listed in the prospectus, no one else is
                  jointly or primarily responsible for the day to day management
                  of fund assets.

Comment: SAI - Portfolio Manager Disclosure
- --------------------------------------------------------------------------------
Comment:          Please disclose modify the disclosure of other accounts
                  managed by the PMs utilizing team approaches to put the focus
                  more on the individual PMs and less on the team, although
                  continue to include a mention of the team aspect of
                  management.

Response:         We will make the modifications discussed on the phone today to
                  address this concern.

Comment:          Tandy Requirements
- --------------------------------------------------------------------------------
