How To Install Service Pack 3 In Windows XP

Check which service pack of windows XP is installed:

(Click Start--> right click My Computer--> and then click Properties).

If Service Pack 3 is listed in the System section, Service Pack3 is already installed on your computer and you don't need to follow the instructions below.

Before we proceed further there are certain things to be taken care.

Log on to your computer using an administrator account, make sure all other users are logged off of the computer, and close all open programs.

Back up your important files to an external location, such as an external hard disk, DVD or CD, or USB flash drive.

Some antivirus software might prevent SP3 from installing, or might slow down the installation. You can try temporarily disabling your antivirus software. If you do so, be sure that you're aware of the risks involved, and be sure to enable it after the service pack is installed.

Make sure you have enough free disk space to install SP3 (even though much of that space will be reclaimed after the installation).
