PowerShell is configured to prevent the execution of PowerShell scripts on Windows systems by default. The PowerShell execution policy is a safety feature implemented to controls the various conditions under which PowerShell loads configuration files and runs scripts. This feature helps prevent the execution of malicious scripts. The execution policy isn’t a security system that restricts user actions. For example, users can easily bypass a policy by typing the script contents at the command line when they cannot run a script. Instead, the execution policy helps users to set basic rules and prevents them from violating them unintentionally.
