To quickly open a new web page in the Internet Explorer, you could define a new function called Show-WebPage like this:
#requires -Version 2 function Show-WebPage { param ( [Parameter(Mandatory = $true, HelpMessage = 'URL to open')] $URL ) Start-Process -FilePath iexplore.exe -ArgumentList $URL }
When you run this script and then enter Show-WebPage, the command asks you for a URL to open. You can also submit the URL as argument to Show-WebPage.
Note how the function uses Start-Process to launch the browser of your choice. If you changed the line to…
Start-Process -FilePath $URL
…then the URL would open in your default browser instead.
