I've been asked to update some computers running Windows XP (without any service packs) to Windows XP SP3. The computers don't have an internet connection (only a small intranet) and have never been updated since first install.
Do I need to install SP1a first, then SP2, then SP3, or can I install SP3 immediately?
And where do I find the right files, that don't require an internet connection during installation?
Best Answer
Here are links to offline installation files for SP1a, SP2 and SP3. Download them on system with an internet connection and use them to update any systems with no internet connection.
If you want to create only single installation disk of all the previous updates including SP3, go to this link to download an ISO image.
