This is a hard way to get it, but it ensures a fast download and a legitimate copy of the final release of Windows Vista Service Pack 1 earlier than the official release date. Follow these steps:
1) Go here: http://www.microsoft.com/oem/enroll.mspx
2) Create a Windows Live account if you don't already have one (if you have a Hotmail or MSN account you already have a Live ID)
3) Go here: https://partners.microsoft.com/PartnerProgram/welcome.aspx and login
4) Enroll yourself as an organization, it asks for a lot of info. Just fill in everything as you see adequate and complete the sign up procedure and you will get confirmation at the end.
5) Go to here: http://oem.microsoft.com/script/agreements...frmcsp0_dvd.img . Login if it tells you to and you get taken to a license agreement page. Accept the license agreement and your download will begin! Its a 1.13GB IMG file that contains the x86 and x64 installers for Windows Vista Service Pack 1. Burn it using Nero or some other burning app that can burn IMG files and install!
Note: Installation of Vista SP1 takes a very long time.
Guaranteed working and is the final release. Screenshot attached. The sign up process is long, but its the fastest assured way to acutally get the final RTM of Vista SP1 (not the build 17xx RC refresh stuff). I used the same method and installed SP1 and it works great
