Conclusion: Windows XP Service Pack 2 introduced some much-needed updates and changes, shoring up millions of PC users' security from the rapidly growing range of threats.
More precisely, on some PCs, it affected the applications that connected to IP addresses from the loopback address range and it triggered an error message informing users that no connection can be established.
Once this update has been installed onto the target computer, it is recommended to reboot it to make sure all changes are applied successfully.
Part of its success relied in its appealing interface, since it was different than the ones that had been available before its launch.
In between these service packs, individual updates were also published, such as Update for Windows XP Service Pack 2 (KB884020) - it goes without saying that in order to install this update, one first needs to have SP2 on their computer, otherwise the installation fails.
