Are you are one the many Windows XP users out there who have been waiting for the official SP3 release from Microsoft. If yes then your waiting is over !
Microsoft has officially released Service Pack 3 for Windows XP.
You can download the stand-alone Service Pack 3 update from Microsoft’s servers now.
If you want to use Windows Update, then you have to wait because Microsoft has yet again delayed the availability of Windows XP SP3 on Windows Update. The problem is apparently due to some conflict between Microsoft Dynamics and Windows.
