I will assume you are using Windows XP. You can go into the Control Panels -> Add / Remove Software and remove the SP2 updates from there. You will have to check the box at the top of the window for "Show Updates" to see the Windows XP updates that are intstalled. But, there are some serious security holes that SP2 addresses and I don't really think you will want to uninstall them simply to get internet access. Sounds like Wanadoo needs to get their act together....or are they some kind of advertising based ISP?
