How to delete a forgotten Content Advisor password

If you have forgotten the Content Advisor password, you can delete it by browsing to this folder in Regedit:
If you are a beginer then remember to backup your registry first

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Ratings
Select the icon called Key in the right-hand pane and press delete. Close Regedit.

You can now start Internet Explorer and goto Tools, Internet Options.... Select the Content tab, and click on Disable. When asked for a password, don't enter anything, just click on OK. This will disable Content Advisor, since there's no longer a password.
