I activated the Content Advisor in IE 4.0, and now I can't disable it because I forgot my password.

There's no way around it: You'll need to edit the Registry, or certain sites will remain out of bounds for you and your family for as long as the Content Advisor stands guard.

Before you start, back up the Registry files: system.dat, system.da0, user.dat, and user.da0.

Select Start-Run, type regedit, and click OK. Go to HKEY_ LOCAL_ MACHINE/ SOFTWARE/Microsoft/ Windows/CurrentVersion/Policies/Ratings. Next, click the Key entry situated in the right window, and press <Delete>. When you have completed these steps, you can exit the Registry and restart your PC.

Once on your desktop, right-click the Internet Explorer icon; then select Properties, click the Content tab, and click Disable Ratings. Don't enter anything when prompted for a password; simply click OK.
