Service Pack 2 (SP2) for Windows XP displays the Information Bar on Internet Explorer when a potentially dangerous actions on a Web page have been blocked.

To control whether an Information Bar message is displayed when a popup is blocked, use the UseSecBand Value Name, a REG_DWORD data type, at HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\New Windows. Setting the data value to 0 will NOT display a message, but setting the data value to 1 will display a message.

You can use Regedit.exe to set the data value 0, or you can:

1. Open a CMD.EXE window.

2. Type the following command and press Enter:

REG ADD "HKCU\Software\Microsoft\Internet Explorer\New Windows" /V UseSecBand /T REG_DWORD /F /D 0

Other Value Names, of REG_DWORD data types, associated with popup messages are:

<b>PlaySound</b>       - A data value of <b>1</b> plays a sound when a popup is blocked. A data value of <b>0</b> disables the sound.

<b>BlockUserInit</b>   - A data value of <b>1</b> blocks popups initiated by a user action, like pressing a link. A data value of <b>0</b> allows these.

<b>AllowHTTPS</b>      - A data value of <b>1</b> allows popups over <b>HTTPS</b>, while a <b>0</b> treats them the same as other popups.

<b>UseTimerMethod</b>  - A data value of <b>1</b> causes a timer to detect user-initiated asynchronous popups.

<b>UserInitTimeout</b> - If <b>UseTimerMethod</b> is set to <b>1</b>, enter the number of milliseconds allowed between
                  a user action and the appearance of the popup.
