I have a powershell script which works just fine in IE however I need to also have it work in Chrome.
$ie = new-object -com \"InternetExplorer.Application\"
Works fine for I
if you are fine with a 3rd party dll you could use Selenium which has also a Chromdriver, that gives you the same kind of control over Chrome as through InternetExplorer.Application COM
Selenium webpage
There is also a PowerShell wrapper for Selenium available on CodePlex
