[SHIP LOGO] [VANGUARD (R) LOGO] P.O. Box 2600 Valley Forge, PA 19482-2600 610-669-1538 Judy_L_Gaines@vanguard.com February 26, 2007 Christian Sandoe, Esq. U.S. Securities & Exchange Commission via electronic filing 100 F Street, N.E. Washington, DC 20549 RE: Vanguard Windsor Funds Dear Mr. Sandoe, The following follows our discussion of February 23, 2007 regarding your comments of February 22, 2007 on the post-effective amendment of the registration statement of the above-referenced registrant. You commented on Post-Effective Amendment No. 108 that was filed on January 8, 2007. Comment: Prospectus - Plain Talk about the Portfolio Managers (Windsor and Windsor II) - -------------------------------------------------------------------------------- Comment: Please clarify the role played by the various portfolio managers. Response: Vanguard uses the term "co-manage" to describe relationships where portfolio managers are truly equals with respect to managing portfolio assets. We will provide additional clarification as necessary when there are distinctions to be made between the roles and responsibilities of a fund's portfolio managers. However, since there are no such distinctions in the case of Windsor and Windsor II Funds, we prefer to leave the descriptions unchanged. Comment: SAI - Portfolio Manager Disclosure - -------------------------------------------------------------------------------- Comment: Please disclose other accounts managed for each PM individually rather than in the aggregate. Response: Some of the investment advisors employed by the Funds utilize team approaches and, in those cases, there are no accounts managed by any individual PMs. In such cases, our SAI disclosure in response to Item 15 is presented at the team level. We have confirmed with the external advisers that no further breakdown by PM is available. The most specific disclosure available is the aggregate amount provided for the investment groups. In response to your comment, though, we will modify the Item 15 disclosure to address each PM individually, explaining that each is responsible for some undetermined portion of the whole. Christian Sandoe, Esq.
