How do I create an object based on the output of a Function in Power Shell?
Function GET-DefaultBrowserPath {
        #Get the default Browser path
        New-PSDrive -Name HKCR -PSProvider registry -Root Hkey_Classes_Root | Out-Null
        $browserPath = ((Get-ItemProperty 'HKCR:httpshelopencommand').'(default)').Split('"')[1]
        return $browserPath
    }

GET-DefaultBrowserPath

$IE = new-object internetexplorer.application
$IE.navigate2("www.microsoft.com")
$IE.visible=$true

$browser_object = new-object -com $browserPath.application

$browser_object = new-object -com firefox.application

Start-Process $url

$path = GET-DefaultBrowserPath
$url = "www.microsoft.com"
&$path $url
