By default, can PowerShell execute scripts written locally on the computer?

• A. Yes, all scripts
• B. Yes, unsigned scripts
• C. No, it does not allow local script execution
• D. No, only digital signed scripts

Answer: (C)

In PowerShell, the default execution policy is set to "Restricted," which means that no scripts are allowed to run, including those that are written locally on the computer. This setting is designed as a security measure to prevent the execution of potentially harmful scripts that could compromise the system. When the execution policy is set to "Restricted," users can still run individual commands in the PowerShell console, but it blocks the execution of any script files. To run scripts, the execution policy would need to be changed to a less restrictive setting, such as "RemoteSigned" or "Unrestricted," depending on the user's requirements. Understanding this default behavior is important for system administrators and users who wish to execute their own scripts safely, ensuring that they are aware of the security implications involved in changing the execution policy.
