If you have Windows Live Family Safety installed and enabled on your Windows 7 computer, and if when it must, Internet Explorer does not display the Windows Live Family Safety block page when a Web site is blocked by Family Safety, then you may have to ensure that Active Scripting is enabled.
Whenever any web page is blocked by Family Safety, Internet Explorer will display a block page warning you about the website. If it does not, then do the following:
Open Internet Explorer > Internet Options > Security tab > Custom Level.
Browse to Scripting section and ensure that Active Scripting is checked.
Click Apply > OK. Restart your Internet Explorer web browser.
It should help!
