    Powershell Scripts in the Windows 10 OS and script execution policy of "Allow only Signed...


    We have the group policy " Turn on Script execution" enabled and set to "Allow only Signed scripts".


    Will this affect the powershell scripts used in the Windows 10 operating System or does windows have something inbuilt that overrides the settings we apply. I'm thinking that it would block even the W10 built in scripts.


    An example of what I am talking about are the 246 .ps1 files in the various diagnostic directories in c:\windows\diagnostics\system\ . our diags never come back with issues even when deliberately disabling components before running.


    other areas that Powershell scripts live that I have found with a quick search -

    C:\Windows\WinSxS\wow64_microsoft.powershell.odatautils_31bf3856ad364e35_10.0.17763.1_none_d60dcab1d9234fab

    C:\Program Files (x86)\WindowsPowerShell\Modules\Microsoft.PowerShell.Operation.Validation\1.0.1\Diagnostics\Comprehensive

    C:\Program Files\WindowsPowerShell\Modules - various folders in here.

    Do we need to sign all powershell scripts that come with the OS?

    Does Microsoft have a method of doing this?

    Is there a list of script files that come with the OS so we don't just do a sign all approach, then find we have signed malware files.

    we could probably configure something in the build task sequence to sign what is there initially. Is there any plan in place for Microsoft to start signing their scripts?

    Will this be an ongoing process as updates are applied and files replaced, do we need to have a process in place to sign all PS1 files in the OS?

    :)

    I ran Option 2 which gave the settings below. How do I reset the permissions back to the default Undefined?

    Set Execution Policy in Powershell

    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 signed
    before they will run.

    Please refer to the link below to know more about Set Execution policy.

    Hope the above information helps.

    Thank you.
