You can actually get the RC version of the service pack from Microsoft now: http://technet.microsoft.com/en-us/windowsvista/bb738089.aspx I was running Vista 64bit and was very excited about the pack but was let down when about 35 minutes later into the install it told me that the service pack didn't install and was rolling back. It made some attempts with over a couple of days with the same results. I finally gave up on Vista. I went back to Windows XP 32-bit.
Thanks for the link. I'll download it tonight and see how it works out and i got vista 32bit so its might work on this.
