Open tab in existing IE instance

Question

$ie = New-Object -com internetexplorer.application

Everytime i open a new website with this object(ie every time when script runs) it is opened in

Answer 1

First you have to attach to the already running Internet Explorer instance:

$ie = (New-Object -ComObject "Shell.Application").Windows() |
      Where-Object { $_.Name -eq "Windows Internet Explorer" }

Then you Navigate to the new URL. Where that URL is opened is controlled via the Flags parameter:

$ie.Navigate("http://www.google.com/", 2048)

Edit: In case 2 or more IE instances are running (additional tabs count as additional instances as well) the enumeration will return an array, so you have to select a particular instance from the array:

$ie[0].Navigate("http://www.google.com/", 2048)

Answer 2

You can use Start-Process to open the URL. If a browser window is already open, it will open as a tab.

Start-Process 'http://www.microsoft.com'

Answer 3

You can use this if Internet Explorer is not your default browser:

Function Open-IETabs {
    param (
        [string[]]$Url
    )
    begin {
        $Ie = New-Object -ComObject InternetExplorer.Application
    }
    process {
        foreach ($Link in $Url) {
            $Ie.Navigate2($Link, 0x1000)
        }
    }
    end {
        $Ie.Visible = $true
    } 
}
