Going to install windows Xp Pro on a new machine. I wonder whether it is better to install Xp and then update to SP3 or better to slipstream SP3 ? I think that by installing Xp and then updating is likely to be the safest but may leave loads of junk behind ( even if I remove the files known to be safe to remove). SlipStreaming may result in a small install but runs the risk of error. any thoughts ?
