powershell execution policy

The PowerShell execution policy is a security feature that controls the conditions under which PowerShell loads configuration files and runs scripts. On Windows 10 and Windows 11, users often encounter errors like "running scripts is disabled on this system" or "the file is not digitally signed" when trying to run scripts. These errors typically occur because the execution policy is set to restrict script execution or because a downloaded script is blocked. Common solutions include changing the execution policy using Set-ExecutionPolicy or using the Unblock-File cmdlet to unblock downloaded scripts. Understanding and managing the execution policy is essential for running PowerShell scripts safely and effectively.
