I deleted myself from the online account of family safety from there I tried uninstalling it from my computer (vista). The problem with that is there isn't a listing for Windows OneCare to uninstall.So,I followed the link to remove Onecare, but I recieved a message saying that I need to be a system administrator. I tired it again while logged into family safety and it still doesn't recognize me as the system adminstrator.

Delete OneCare Family Safety settings
Only the primary administrator(Family Safety users with permissions to change Family Safety settings, and to add and remove child users. The primary administrator can also add and remove secondary administrators.) can delete OneCare Family Safety child safety settings(Customizable settings that help parents to protect children from being exposed to inappropriate web content. For example, parents can block access to specific types of content on the Internet.) from the Family Safety website. Other administrators and child(An account holder whose use of the Internet is restricted by Family Safety. Children can't view their own child safety settings.) account holders don't have permissions to delete these settings. Family Safety isn't completely deleted until the Family Safety software(Downloaded software that enforces child safety settings and content filtering based on the settings defined on the Family Safety website. Users must sign in to the Family Safety software to use the Internet on the computer the Family Safety software is installed on.) is uninstalled from every computer on which it was installed.
On the OneCare Family Safety home page, click Returning user, and then sign in with your Windows Live ID (A user name and password used to sign in to any Windows Live product or service. Family Safety uses the Windows Live ID to identify the person signing in, and to match them with their individual settings.) . Don't select the Remember my password check box, or child users will be able to sign in and use your account.
Click Delete settings, and then follow the on-screen instructions.
