Tips a easy to clear IE Security Password _ registry in the registry

Some friends like the IE browser's "Content Advisor" feature to open and set password ("internet options → contents → rating review"). In this way, when you display a page with "ActiveX", you will always receive a "Content Advisor does not allow view" message, and then the Password dialog box will be displayed, asking you to enter the Guardian password. If the password is not correct, stop browsing.

However, if this password is forgotten, the pages cannot be browsed. The security password cannot be removed even if the Internet Explorer is reinstalled. At this point, you can use the registry to clear. Run the Regedit.exe command, open the Registry Editor window, locate the HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies branch, Policies select the "ratings" subkey, press the "Del" key to delete it, because the "key" key value of "ratings" keys is encrypted after the password, deleted the subkey, ie browser naturally think we have not set the password.
