How can I change the policy that will allow me to run the PowerShell script on my machine? PowerShell screen

I have tried checking the solution described there:

How do you successfully change execution policy and enable execution of PowerShell scripts

I changed the settings in MMC (Computer Configuration -> Administrative Templates -> Windows Components) and regedit (HKEY_LOCAL_MACHINE -> SOFTWARE -> Policies -> Microsoft -> Windows -> Powershell)

but all the time I am getting that error on the attached screen

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 RemoteSigned. Type "Get-ExecutionPolicy -List" to view your execution policy settings. For more information p p lease see "Get-Help Set-ExecutionPolicy". At line:1 char:46

HKEY_LOCAL_MACHINE -> SOFTWARE -> Policies -> Microsoft -> Windows -> Powershell changed to "ByPass"

Try this and work up.

Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope Process

You can try other values for scope.

Get-Help Set-ExecutionPolicy -Parameter scope

Get the values for the enum listed for that parametr:

[Microsoft.PowerShell.ExecutionPolicyScope]::GetValues([Microsoft.PowerShell.ExecutionPolicyScope])

it worked. But now if I have few PowerShell scripts and I want to create a sequence and run them one by one after they are finished how can I do that? for example I have three scripts one.ps1, two.ps2, three.ps1 and I want a sequence: one.ps1 - wait for the end and then run next, two.ps1 - wait for the end and then run next, three.ps1
Probably depends on what scope worked for you. Generally if you set it in a session, it will apply to that session and children so you can just call the three scripts.

  • You've (successfully) updated your script execution policy via a GPO (Group Policy Object; via MMC, as described in your question).

  • GPO-based execution policies have the highest precedence among all the scopes in which you can set a policy; Get-ExecutionPolicy -List shows the scopes in descending order of precedence (among the two GPO scopes, MachinePolicy takes precedence over UserPolicy).

  • Your error message shows an attempt to set the execution policy for the current process (-Scope Process).

  • Because an execution policy in the process scope is overridden by GPO-based execution policies, the process-level attempt is ineffective, and that's what the error message is trying to tell you.

  • You can ignore the error if the GPO-based execution policy is still permissive enough to allow you to run your script, but I suspect that the process-level attempt to set the execution policy stems from running your scripts via File Explorer's context menu, whose invocation command is - unfortunately - defined that way.

    • You can try to modify the invocation command via the registry (HKEY_CLASSES_ROOT\Microsoft.PowerShellScript.1\shell\0\Command) and remove the Set-ExecutionPolicy call from it.
