Remember, XP was launched in 2001 and it reached end-of-life on the 8th of April, 2014?
Service Pack 3 is a cumulative update (includes all previously released fixes), therefore you do not need to install Windows XP Service Pack 1 or 2 before proceeding with Service Pack 3 installation. If you already have Service Pack 3 installed, you can safely skip this article.
As of June 2017, the latest major update for Windows 8 is Windows 8.1 Update.
The latest service packs for other versions of Microsoft Windows include Windows Vista SP2, Windows XP SP3, and Windows 2000 SP4.
