Once I downloaded the Service Pack 3, and then after Extracting Files I got an error that read, Service Pack 3 error...Setup has detected that the version of the Service Pack installed on your system is lower than what is necessary to apply this hotfix. At minium, you must have Service Pack 1 installed. OK I clicked ok to continue. I rebooted checked Window Updates again nothing happened. I then tried to download one of the older versions of service pack 3 that we loaded a few weeks ago, and got the same thing again. Still nothing on the Windows Update.
