i have tried to download and install windows XP service pack 1 15 times and it fails everytime, anyone know why? thanks

Did you follow this: To prepare for an SP1 installation (from M$) 1. If you use Faster User Switching, make sure that all other users are logged off from the computer and that only you are logged on to the computer; you must be logged on as an administrator. 2. In the event that the installation fails, you need to ensure that you get the most out of data recovery. On computers running Windows XP Professional, to maximize data retrieval, create an Automated System Recovery (ASR) before you begin installation. For detailed instructions, see "To create an Automated System Recovery set using Backup" or "To recover from a system failure using Automated System Recovery" in Windows XP Help and Support Center. 3. Perform a full backup of the files that you keep on your computer. 4. Stop any real-time virus checkers before you install SP1 because they might interfere with your installation. (Be sure to restart the virus checkers after you install SP1.) Check the space requirements for installing SP1 on your computer. See article Q326583, "Hard Disk Space Requirements for Windows XP Service Pack 1," in the Microsoft Knowledge Base. Important Automated System Recovery (ASR) will not restore your data files. For more information, see "Backing up files and folders," "Restoring files and folders," and "To create an Automated System Recovery set using Backup" in the Windows XP Help and Support Center. Caution Before you begin the installation, remember to perform a complete back up of all your files on your computer and close all open programs.

Are you on dailup .I am and finnally gave it up. Just be sure and delete the uplddrvinfo.htm file and dont worry about it. With all the problems people are haveing after installing it I will not install untill they get the bugs worked out I figure that will be about the time I get the CD they said 6-8 weeks and then send me an email saying it is on backorder.

See this thread (and my solution): http://www.computing.net/windowsxp/wwwboard/forum/40079.html

I could NOT install SP1 until I removed un-did some (Regsvr32) tweaks from 'XP-AntiSpy' I think it saw my machine as a un-registered version and stopped! Hope this helps some! Czar
