Configure PowerShell Settings

Recently, we needed to start building select machines off of our domain for special projects. This meant that group policies would not be applied. I use GPOs to set PowerShell settings on all of the machines. With these machines no longer getting GPOs applied, PowerShell scripts would no longer execute correctly because some of my scripts also use a module I push via GPO and the execution policy was not updated. This lead me to write, with the help and ease of Sapien's PowerShell Studio, the script below that will set the execution policy, configure the RunAs Administrator, configure additional paths for PowerShell modules, and copies PowerShell modules over. This gets executed after the first windows updates are applied in the task sequencing. If the script is executed manually, there is an output screen that shows if each setting is a success or failure.

To use this script, you will need to update/verify lines 212, 217, 224, and 225. Of course, if you don't want all of those things to change, you can comment some of them out.

You can download the script from here.
