Here is a PowerShell script that you can use to open IE with multiple tabs on start-up:
$navOpenInBackgroundTab = 0x1000;
$ie = new-object -com InternetExplorer.Application
$ie.Navigate2("http://pkm-technology.nl");
$ie.Navigate2("http://khabbazi.nl", $navOpenInBackgroundTab);
$ie.Navigate2("http://khabbazi.nl/blog", $navOpenInBackgroundTab);
$ie.Visible = $true;
