How to install Windows Media Player 11 without Windows Authentication We receive a lot of emails about installing Windows Media Player version 11 on a computer that has not passed Windows authentication. The problem is that when you download Windows Media Player version 11 from a Microsoft server (wmp11-windowsxp-x86-enu.exe) so during installation your welcome to Windows authentication. The joke is that ... ... the authentication mechanism is only in the installation package (wmp11-windowsxp-x86-enu.exe), just rename this file to wmp11-windowsxp-x86-enu.cab and expand it using Total Commander, and then run wmp11.exe (Windows Media Player 11) and wmfdist11.exe (Windows Media Format 11 Runtime).
