You will probably not see much difference in SP3 over SP2. Much of what these updates are about has to do with improving security and correcting problems that cause applications to crash.
How long will it take to install?
It could take 30 minutes or longer, depending on what version of XP you have and what steps you will need to perform before installing the update.
Will SP3 damage my file system? Should I backup my files before upgrading?
It is unlikely that the update will damage your files. However, you should ALWAYS backup your work so that files are located in two different physical places (such as on your PC and on a CD or other computer).
It is important that you read and follow these directions before installing the SP3 update.
