On 4/22/08, Microsoft showed the update gold shield telling us to download/install and update. I proceeded to use Microsoft Update and the system scanned our laptop Acer Aspire AMD base. After a long wait it inform us that we had the SP3 to be installed. Proceeded to install it and although I understand it is a large release, it took over 1.5 hrs to come back with the Service Pack 3 Setup Error: "A device attached to the system is not functioning". It does not tell you what device, just to select OK to Remove Changes. It goes to another long, long time before indicating that it failed. Now, over four weeks later, another gold shield showed up about SP3. Follow the same process as before, and after 1.5 hrs, came back with the same SP3 Setup Error. It is obvious that it is detecting something but it does not help you to know what you can do. Any suggestions? ZoneAlarm, BitDefender, Scan with , SpyBot

You can try gutting out your computer guts and try installing SP3. MS has been having installation problems with SP3

Go to the Microsoft website & download the full version of SP3...do NOT get it from Windows update. Burn the ISO file to a CD using Nero or ImgBurn, then do the installation from the CD: http://www.microsoft.com/downloads/... "And that's the fishing line, because Sharkboy said so!"

Ok then in that case I just want to know the benefits for installing SP3 over SP2 like for example getting a Cannot lock volume or cannot do a Sytem Restore becasue the pc is in use by another procces
