PowerShell

Set-ExecutionPolicy Unrestricted -Force

You try to run your script

./your_script.ps1

And you get

.\your_script.ps1 : File C:\Users\Andrei\your_script.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see about_Execution_Policies at https:/go.microsoft.com/fwlink/?LinkID=135170. At line:1 char:1 + .\your_script.ps1 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess

You need to open PowerShell as administrator and run

Set-ExecutionPolicy Unrestricted -Force

And run it once more

./your_script.ps1

If you cannot run PowerShell in administrator mode. For example, if you use the terminal in Visual Studio Code

Run

Set-ExecutionPolicy -Scope CurrentUser Unrestricted -Force

You can switch PowerShell to Administrator mode right from a regular PowerShell console with the command

start-process powershell -verb runas
