Hi,
in Powershell Studio i exported my script with the deploy function. After them i transfered the exported script to a test system where i run it. At the begin i get an 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 more
information please see "Get-Help Set-ExecutionPolicy".

The execution policy on my test system is unrestricted. Has anyone an idea where i can configure the execution policy option for deployment in Powershell studio. Powershell Studio does not change the execution policy on the target system. It's controlled by group policies.
I' dont want to override my own security policy. If i open the deployed script and i'm looking at line 1 char 46 - i cannot find anything to change the execution policy. At line 1 is a comment.
The default policy is "RemoteSigned" but for testing i use "Unrestricted" in an isolated environment.
Yes i know that i can change the policy to execute a script. I tested again and recognized that the problems source is not my Powershell Studio script. A little three liner shows the same error. So i have to search for this error in my policies.
Changing the policy in a script is not how this works. If a script runs then the policy allows it. Any change to the policy will not affect the current script. The command is a system configuration command. When it works it is permanent.
If a policy is set for the system then the user can only set a more restrictive policy but will get an error or warning when trying to set a less restrictive policy.
"Bypass/Process" is a one time policy shot that affects a script before it is run which is why it works on the command line. It will also work for any new scripts called from the current PowerShell process. If you can run an unsigned script that is on the local file system then there is no need to "Bypass" except if you want to call a remote unsigned script from that PS session. If GP has set "RemoteSigned" then the remote script will still run because you have permission to Bypass. All admins can "Bypass".
There should never be a need to set this in a script if the systems are configured for the correct security required by the organization which would normally be "RemoteSigned" or "AllSigned".
A standard user can set Bypass with no prompt or error by using "Force"
Set-ExecutionPolicy bypass -Scope Process -Force
Check the PowerShell Team blog for more information on how policy works. Note that these policies are not hard security restrictions since they can be bypassed. They are a first defense against rogue scripts. Even a fully restricted policy still allows a text file to be loaded into memory and executed from memory.
