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:

PlaySound       - A data value of 1 plays a sound when a popup is blocked. A data value of 0 disables the sound.                              BlockUserInit   - A data value of 1 blocks popups initiated by a user action, like pressing a link. A data value of 0 allows these.                              AllowHTTPS      - A data value of 1 allows popups over HTTPS, while a 0 treats them the same as other popups.                              UseTimerMethod  - A data value of 1 causes a timer to detect user-initiated asynchronous popups.                              UserInitTimeout - If UseTimerMethod is set to 1, enter the number of milliseconds allowed between                                                a user action and the appearance of the popup.
