Part 2: Directory Listing

For this part of the lab we will be running scripts in powershell. The PowerShell Execution Policy is set to "restircted" by default on windows. This is a security policy that prevents all scripts from running. We must disable this policy to be able to run the scripts for this part of the lab! To do so, type in the following:

// Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine

To write PowerShell scripts, we can use PowerShell Integrated Scripting Environment (ISE) which allows use to write, run and debug PowerShell scripts!
