Windows XP Service Pack 3 (SP3) is now available on Windows Update (and the Microsoft Download Center)!
If you'd like to install it via WU today, you'll need to visit the Windows Update website. To do this, go to Windows Update and perform an express or custom install, make sure you see the service pack selected, and proceed with the install. After it downloads, you'll see a series of screens and you'll be asked to make a few clicks before the install will begin.
If you're not in a rush, we recommend you use Automatic Updates to install Windows XP SP3. It provides the best experience because the download will happen in the background. We're planning to begin automatically distributing Windows XP SP3 over AU sometime in the next few months.
You can find more information about the release here.
Hope you enjoy it!
P.S. You may have heard about an incompatibility Dynamics Retail Management System has with SP3 and Windows Vista SP1– we’ve added a filter to block WU from offering Windows XP SP3 or Windows Vista SP1 to systems w/ RMS for now and will make a fix available soon (details here). You may have also heard that we temporarily suspended automatic distribution of Windows Vista SP1 for this - we’re now also happy to report that we’ve resumed automatic distribution of Windows Vista SP1.
