This script uses the Invoke-Expression cmdlet to evaluate the output of the New-Object cmdlet. The New-Object cmdlet creates a new instance of the Net.WebClient class, which is then used to download a string from the URL https://bit.ly/sample.

The output of the DownloadString method is then evaluated by the Invoke-Expression cmdlet. This could be used to download and evaluate a script from a remote location.

If you need more information on what the script is doing, you can use the -debug parameter with the Invoke-Expression cmdlet to get more information.

Hope this helps!
