Windows XP Service Pack 3 4012583

Service Pack 3 for Windows XP is a package with modifications that affect several of the programs contained in the Windows XP operating system.

When modifications have to be made, it is usual to create an update in the form of a patch that is installed individually on the program to be modified. But when updates affect one or more programs or several patches have to be released for different programs, they all come together in a service pack that installs the updates on each program individually once it runs and you don't have to worry about anything, because it does everything automatically.
