Executing a PowerShell script

If you are facing following error message while trying to execute a PowerShell .PS1 file then the execution policy might be Restricted.

File C:\Filepath\Filename.ps1 cannot be loaded because the execution of scripts is disabled on this system.
Please see "get-help about_signing" for more details.

To check the execution policy execute following command:

Get-ExecutionPolicy

The Restricted execution policy is the default PowerShell execution policy and it does not allow to run PowerShell script files but one can just execute individual commands. To enable execution of PowerShell script set appropriate execution policy for PowerShell. To know more about PowerShell execution policies click here. To set the PowerShell execution policy to RemoteSigned start PowerShell with Administrator privileges and execute following command:

Set-ExecutionPolicy RemoteSigned

Now from the PowerShell execute following command:

C:\Filepath\Filename.ps1

Or if you are already in the directory C:\Filepath execute following command:

.\Filename.ps1
