Well If you have read my previous Hack Attack on How you can download Windows Vista SP1 through a Hack and it worked for you then here is another Hack that will allow you to download Windows XP SP3 RC1 directly from Microsoft. Windows XP SP3 will be the final service pack that we will see for the World’s biggest Operating System from Microsoft. SP3 will bring a host of bug fixes and some new features borrowed from Vista.
Getting Windows Vista SP1 is old news, but apparently you can also get Windows XP SP3 the same way. All you need to do is to edit the registry to make Windows Update think that you're a Beta tester, and then you'll be able to download the Service Packs early.

Please note that the service packs are in Beta and have many problems with them. This is just for those people who are developers and would like to try the Service Pack out.

Silly Microsoft.

*Excuse me if this is old news to you. I haven't been paying attention to technology news due to Black Friday and Thanksgiving.
