Windows XP SP3 is in the
news since few days now.
The theme of this post is to bring to your notice the fact that Windows Service Packs are cumulative and includes all updates from the previous ones.
This means that if, for example, your XP CD has neither SP1 nor SP2 integrated, you can still go ahead and install Windows XP SP3.
Windows XP Service Pack 3 (SP3) is now available for download and install via Windows Update and the Microsoft Download Center. Windows XP SP3 includes all previously released updates for the operating system, in addition to a small number of new updates. Windows XP SP3 will not significantly change the Windows XP experience.
