File Description: WinXP SP1 beta. Contains all bug and security patches in addition to additional features. The program will download the files you need to update to SP1. SP1 is in beta status right now and will expire in 180 days. By then the official release will be out. You cannot install SP1 beta (it will also disable windowsupdate) if you used the leaked volume license key (FCKGW...) in your WinXP install.
