Update for Windows XP Service Pack 2 (KB884020)

Windows XP was launched in October 2001 and it became one of the most popular operating systems on a worldwide scale. Part of its success relied in its appealing interface, since it was different than the ones that had been available before its launch.
Another reason for its popularity was that the development teams at Microsoft were constantly working on improving its stability and solving its bugs, so as to ensure the user experience was not affected.
This is why Microsoft released no less than 3 service packs for this OS, while also encouraging all users to install all of them to benefit from increased security and stability.
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.
The reason why this update was so important that it warranted a separate release was that it dealt with connection issues. 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.
It also needs to be mentioned that support for Windows XP stopped in April 2014, so all users are advised to migrate to a newer one to prevent any potential security flaws that leave them vulnerable in front of malware attacks. .
