After apparent successful installation of SP1 through Windows Update, I found that I had no connection to the Internet. (Cable broadband, hard-wired router.) I did a system restore and was once again able to get online. I don't want to re-install SP1 until I know what caused the issue. Any help would be much appreciated. Don't know if you need any further info, and hope this is the right thread - I'm fairly new to all this. Thank you in anticipation.
