As an IT Professional using PowerShell to write scripts and automate tasks, it is important that you have a good understanding on how PowerShell execution policies work. PowerShell’s execution policy is a safety feature that controls the conditions under which PowerShell loads configuration files and runs scripts. This feature helps prevent the execution of malicious scripts as it acts as the gate-keeper.<\/p>\n
