I have a 4 year old Dell desktop that was running slow so I reinstalled Vista from the D: drive. Everything went fine and I was able to download all of the updates except Service Pack 1. It keeps popping up and asks to be installed which I allow and then it says update successful. Then the next time I reboot it shows SP1 is ready to update. The update history shows a successful install for SP1 but windows properties does not indicate SP! installed plus when I installed it, it said it would take several hours to install but it only took a few minutes. I'm confused, can I even get SP1 through windows update since they quit supporting it in 2011. Any insight would be appreciated.
