I have a startup script that runs during Window Sandbox startup that sets the execution policy while I am in that session.
$E = $ErrorActionPreference
$ErrorActionPreference = 'SilentlyContinue'
if ((Get-ExecutionPolicy -Scope LocalMachine) -ne "Unrestricted") {
Set-ExecutionPolicy Unrestricted -Scope LocalMachine -Force # Will always error if CurrentUser scope is set already
}
$ErrorActionPreference = $E
However, everytime tht script rung inside the Windows Sandbox, I get the following 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 Bypass. Type "Get-ExecutionPolicy -List" to view
your execution policy settings. For more information please see "Get-Help
Set-ExecutionPolicy".

When I list the policy inside the Sandbox session, I get:

Why is the policy that I am trying to set, not being set (apparently)? Maybe the LocalMachine policy is being picked up from the Host system, but if so, how can I override that (this script the startup script that always runs with elevated privileges after all!)?
I am trying to set the execution policy to Unrestricted, but I'm getting the following error:

Execution Policy Change
The execution policy helps protect you from scripts that you do not trust. Changing the execution policy might expose
you to the security risks described in the about_Execution_Policies help topic at
http://go.microsoft.com/fwlink/?LinkID=135170. Do you want to change the execution policy?

'HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\PowerShell\1\ShellIds\Microsoft.PowerShell' is denied. To change the execution
policy for the default (LocalMachine) scope, start Windows PowerShell with the "Run as administrator" option. To
change the execution policy for the current user, run "Set-ExecutionPolicy -Scope CurrentUser".

Set-ExecutionPolicy defaults to setting the script execution policy for the whole system (implied -Scope LocalMachine).
-Scope LocalMachine can only be used from an elevated session (run as admin);[1] if your session isn't elevated, you'll get the error you saw - and the error text actually both explains the problem and provides instructions for how to resolve it.
To summarize:
Either: Re-run your command from an elevated session, assuming you have administrative credentials.
You can start one with Start-Process powershell -Verb RunAs (use pwsh in PowerShell (Core) 7+).
Or: Change the persistent execution policy only for the current user (-Scope CurrentUser)
Set-ExecutionPolicy -Scope CurrentUser RemoteSigned -Force
Note:
I've chosen RemoteSigned as the policy in the sample call, as it provides a balance between security and convenience: it places no restriction on local scripts, but prevents execution of scripts downloaded from the web that aren't cryptographically signed.
-Force bypasses the interactive prompt.
While a current-user execution policy takes precedence over a local-machine one, both can be preempted by GPO-based policies - see this answer for more information.
There's also a way to set the execution policy for a single session only, via -Scope Process, though that is typically used via the PowerShell CLI (powershell.exe for Windows PowerShell, pwsh for PowerShell (Core) 7+), in the form of -ExecutionPolicy Bypass.
[1] While the same applies to PowerShell (Core) 7+ in principle, elevation is not required if you happen to have installed it in a current-user location. Also note that execution policies fundamentally do not apply when you use PowerShell (Core) 7+ on Unix-like platforms.
This question already has answers here:
PowerShell says "execution of scripts is disabled on this system."

When I try to run ionic commands like ionic serve on the VS Code terminal, it gives the following error.
How can I fix this?
ionic : File C:\Users\Lakshan\AppData\Roaming\npm\ionic.ps1 cannot be loaded because running scripts is disabled on this system. For more information, see

I found a way to fix this error.
It is as follows:
First, Open PowerShell with Run as Administrator.
Then, run this command in PowerShell
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned
After that type Y and press Enter.
This is because of Execution Policy. This defines how powershell scripts will run.
In Default windows desktops, it is Restricted, not allowing any scripts (signed or unsigned) only interactive sessions.
So best is you set using RemoteSigned (Default on Windows Server) letting only signed scripts from remote and unsigned in local to run, but Unrestriced is insecure lettting all scripts to run.
To set run Set-ExecutionPolicy -ExecutionPolicy RemoteSigned as administrator.
This code will fix it:
Set-ExecutionPolicy RemoteSigned –Scope Process
To Bypass this you need to change the Execution policy.
Type this into your terminal.
Set-ExecutionPolicy -Scope CurrentUser
then it will prompt you to supply a value at which point you can set Bypass / RemoteSigned or Restricted.
cmdlet Set-ExecutionPolicy at command pipeline position 1
Supply values for the following parameters:
ExecutionPolicy: "RemoteSigned" or "Bypass" or "Restricted".
I am getting below error while running any powershell script. It's happening on only one of the client's servers. I am not sure what is triggering this command.
If I change this registry key from RemoteSignedto to ByPass error goes away.
Set-ItemProperty -Path HKLM:\Software\Policies\Microsoft\Windows\PowerShell -Name ExecutionPolicy -Value ByPass
For example I have below simple script of one line.
Read-Host -Prompt "Hit Enter to exit"
Set-ExecutionPolicy : Windows PowerShell updated your execution policy successfully, but the setting is overridden by

You need to Run as Administrator and then try to Set-ExecutionPolicy..
or you can run powershell by this way also :
powershell.exe -ExecutionPolicy bypass
or
Set-ExecutionPolicy -ExecutionPolicy Bypass -Scope CurrentUser
I have a power shell script that runs to stop services, 'stop / terminate process' , delete 2 files and then restart.
I can run this script perfect on my Windows 10 64 Bit Host Machine - with ZERO issues.
I try to run it in my Virtual Machines and I get the error
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
SO just for giggles I went to see my group policies and they are not configured on either machine.
Administrative Templates > Windows Components > Windows PowerShell
Not Configured.
So why the issue on the virtual machine and not in my host ?
EDIT
Ran Get-ExecutionPolicy and also Get-ExecutionPolicy-List on VM
Restricted
MachinePolicy Undefined
UserPolicy Undefined
Process Undefined
CurrentUser Undefined
LocalMachine Undefined
Ran it on my Host
Scope ExecutionPolicy

MachinePolicy Undefined
UserPolicy Undefined

I do not know how my local machine was changed - software installation ??
The following will allow all local scripts to execute on the VM, irrespective of whether they're signed or not:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
I am going to go out on a limb here and just rehash a portion of About Execution Policies.
The default execution policy for Windows client OSes is Restricted. This means that a script will not run automatically. If your VM has a Windows client OS and you have never changed the execution policy, then your issue is expected. If the one Windows 10 machine works without issues, then someone changed the execution policy.
On the problematic VMs, you will need to determine the scope (or account) that is running your script. Then you will need to set the execution policy accordingly.
If you are testing running a script while logged into the server as yourself, then you can just open a PowerShell console and run the following:
Set-ExecutionPolicy RemoteSigned -Scope CurrentUser
Then run the script in that same console.
The following command will list the execution policy for all scopes on that machine:
Get-ExecutionPolicy -List
You should compare the command above on the working system and the non-working system. Your issue likely be the execution policy setting for the particular scope that is running the script. If you read the link in my post, it should help you determine what you need to change specifically.
If you are on Windows here is what you have to follow:
Press the [windows] button and then type PowerShell.
Run as Adiministrator
Copy and Paste the following command and hit [Enter]
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Type Y and hit [Enter]
Rerun the command and type A hit [Enter]
Close the powershell and try again
Good luck.
Open your PowerShell and enter the following command
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
I had the same problem with VS Code then I check the cmd with Administrator run. There is no problem so better to use CMD easy way to pass this problem
Run Powershell as an administrator and run the following command:
set-executionpolicy remotesigned
The least problematic approach is to use the command:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
This will get around Admin user authority issues.
After running powershell as administrator, run the following commands:
Get-ExecutionPolicy -List
Set-ExecutionPolicy Unrestricted
Set-ExecutionPolicy Unrestricted -Force
May be you need to restart the machine.
Open your powershell as an administrator and then paste those commands:
Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Then choose A
I had the same issue in my PC. Open the windows PowerShell ISE in administrator mode and run Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
This command solved my issue.
I had same issue when trying to create a vue application by running vue create my-project
To fix this I have followed below steps
Open powershell as an administrator on Windows
Run this command - Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine
Now open a new session on your terminal and run your application specific script. It worked.
user powerShell as admin and execute the following commends:
1-Set-ExecutionPolicy RemoteSigned
2-Get-ExecutionPolicy -List
3-Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope LocalMachine*
and rerun the scrips again and it will work
I m just farwarding all the changes that implies with setting the ExcecutionPolicy to RemoteSigned with the command : Set-ExecutionPolicy -ExecutionPolicy RemoteSigned ( I really recommend to first give a look at the other policies offered : Windows Execution Policies )
RemoteSigned :
The default execution policy for Windows server computers.
Scripts can run.
Requires a digital signature from a trusted publisher on scripts and
configuration files that are downloaded from the internet which
includes email and instant messaging programs.
Doesn't require digital signatures on scripts that are written on the
local computer and not downloaded from the internet.
Runs scripts that are downloaded from the internet and not signed.
Risks running unsigned scripts from sources other than the internet
and signed scripts that could be malicious.
Note that on Windows, browsers sign downloaded files and mark them as 'coming from the Internet'. If u want to unblock such a script, u can use the cmd Unblock-File.
user powerShell as admin and execute the following commends:
PS C:\WINDOWS\system32> Get-ExecutionPolicy -List
Scope ExecutionPolicy
----- ---------------
MachinePolicy Undefined
UserPolicy Undefined
Process Unrestricted
CurrentUser Unrestricted
LocalMachine Unrestricted
To unrestrict the execution policy:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope Process
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope CurrentUser
Under your normal user. The following requires to open an administrator instance:
Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope LocalMachine
as an administrator.
You might need to restart the computer afterwards.
You will see peerjs server is working
Use the syntax below
Set-ExecutionPolicy -Scope CurrentUser
Enter the "Unrestricted" as your value in the ExecutionPolicy parameter syntax below:
ExecutionPolicy:Unrestricted
Then run your command; you can check the node version or any version of the software you installed after implementing the commands above
I have tried these two ways that you can tackle this problem succesfully:
By enabling PowerShell execution policies:
PS C:\Users\usr1>Set-ExecutionPolicy -Scope CurrentUser -ExecutionPolicy Unrestricted
For example, I encountered this problem when i wanted to run yarn command at my project's root folder. Then by running the command above, I was abled to run the comand yarn without a problem.
Use bash terminal instead of powershell terminal
You can use this method when you get error from the powershell terminal by running the Set-ExecutionPolicy command. Like the error below:
In such case, by switching your terminal to bash you can have your scripts run:
