Last month we told you that it was possible to download Windows Vista SP1 by altering your Windows registry settings. Now it looks like a new registry hack is making the rounds. This one will let Windows XP users download Service Pack 3 for Microsoft's older, but generally more stable operating system.

Both the Vista and XP service packs aren't scheduled for wide release until early next year. In other words, downloading a pre-release copy might really not be the best idea. Sure, it'd be nice to grab a software update intended to improve your system's reliability and security. But since these updates are still in beta testing, you could wind up causing more problems than you solve.

That said, it looks like the registry hack is pretty straightforward. Just download a patch, look for Windows Updates, download them and reboot your computer into glorious SP3 bliss. And by bliss, we mean a few new features like a new Windows Product Activation module, a Network Access Protection module (ported from Vista), and cryptographic algorithm support in the kernel. We know, it all sounds so glamorous.
