You are unable to hide the Address Bar in Internet Explorer 7.0.

In Internet Explorer 6, you may use the NoAddressBar registry value which is mentioned in the KB article 823057 to remove the Address bar. This works in Internet Explorer 6. However, it does not work in Internet Explorer 7.0.

In Internet Explorer 7.0, the design is changed. You may refer to the information in the Resolution section of this article to disable the Address bar.

In Internet Explorer 7, you can use the "NoNavBar" registry value to disable the Address bar.

For a “Per User” setting, the value is located in the following key:

[HKEY_CURRENT_USER\Software\Policies\Microsoft\Internet Explorer\Toolbars\Restrictions]

Value name: NoNavBar
Value Type: DWORD
Data: 0x00000001

For a “Per Machine” setting, the value is located in the following key:

[HKEY_LOCAL_MACHINE\Software\Policies\Microsoft\Internet Explorer\Toolbars\Restrictions]

Value name: NoNavBar
Value Type: DWORD
Data: 0x00000001
