Internet Explorer 7 does not support a built-in command to open multiple tabs at startup. Although you can specify multiple URL’s as default homepages, this might not be what you want.
A solution to open several tabs at once for only one time, can be made with Windows Scripting Host, or wscript.
First, create a new text document with Notepad or some other text editor and add the following content:
var navOpenInBackgroundTab = 0x1000;
var oIE = new ActiveXObject("InternetExplorer.Application");
oIE.Visible = true;
Save the file as launchie7.js (so change the extension from *.txt to *.js) to your C:\ drive
To launch Internet Explorer with multiple tabs, run the following command from Start – Run:
Of course, if you chose another destination to save your launchie7.js, you should specify that specific path.
