Powershell Set Execution Policy

• Set an execution policy value of Undefined to effectively remove the execution policy that is set for the current user scope. As a result, the execution policy that is set in Group Policy or in the LocalMachine (all users) scope is effective: PS C: set-executionpolicy -scope CurrentUser -executionPolicy Undefined.
• If you set the execution policy to all scopes to Undefined, then the execution policy that will be in effect is Restricted, which is the default execution policy. Set execution policy for one session The parameter -ExecutionPolicy of powershell.exe, allows you to set a different execution policy for the new session.

1. Windows Power Shell Set Execution Policy

Hi,Thank you for posting your query in Microsoft Community.I will surely assist you with your query.The execution policy is part of the security strategy of Windows PowerShell. It determines whether you can load configuration files (including your Windows PowerShell profile) and run scripts, and it determines which scripts, if any, must be digitally signedbefore they will run.Please refer to the link below to know more about Set Execution policy.Hope the above information helps.Thank you.

While setting up execution policy (Set-ExecutionPolicy) on powershell, there might be a below error.Set-ExecutionPolicy: Windows PowerShell updated your execution policy successfully, but the setting is overridden by a policy defined at a more specific scope. Due to the override, your shell will retain its current effective execution policy of Unrestricted. Type 'Get-ExecutionPolicy -List' to view your execution policy settings. For moreinformation please see 'Get-Help Set-ExecutionPolicy'.At line:1 char:1+ Set-ExecutionPolicy Restricted+ + CategoryInfo: PermissionDenied: (:) Set-ExecutionPolicy, SecurityException+ FullyQualifiedErrorId: ExecutionPolicyOverride,Microsoft.PowerShell.Commands.SetExecutionPolicyCommandThis error appears due to below 2 reasons.1) If different execution policy is setup at execution Scope level (Process, CurrentUser or LocalMachine) using cmdlet Set-ExecutionPolicy, as shown in. MachinePolicy and UserPolicy can only be changed and setup using Group policy as shown in 2nd point.2).To resolve this issue, change the manual execution scope of Process, CurrentUser or LocalMachine to undefined. Undefined means there is no execution policy set in the current scope. If the execution policy in all scopes is Undefined, the effective execution policy is Restricted, which is the default execution policy.

If you (or a helpful admin) runs Set-ExecutionPolicy as administrator, the policy will be set for all users. (I would suggest 'remoteSigned' rather than 'unrestricted' as a safety measure.) NB.: On a 64-bit OS you need to run Set-ExecutionPolicy for 32-bit and 64-bit PowerShell separately.

Windows Power Shell Set Execution Policy

Running only Set-ExecutionPolicy without scope syntax changes LocalMachine by default and if tried to modify it, it will always generate error if Group policy is setup.Current scope list can be viewed using command Get-ExecutionPolicy -List and changing the policy doesn't show error Set-ExecutionPolicy Undefined -Scope CurrentUser.If all scope policies are set to undefined (except LocalMachine), changing configuration will not show any error.Useful Articles.
